NAME

       POSIX::2008 - Perl interface to POSIX.1-2008

SYNOPSIS

         use Fcntl;
         use POSIX::2008 qw(openat pwrite);

         sysopen my $dh, '/tmp', O_RDONLY|O_DIRECTORY|O_NOFOLLOW or die 'Dafuq?';
         my $fh = openat($dh, 'foobar', O_RDWR|O_CREAT);
         pwrite($fh, 'fuckyounsa', 10, 0);

DESCRIPTION

       POSIX::2008 contains many of the interfaces specified by POSIX.1-2008
       <http://pubs.opengroup.org/onlinepubs/9699919799/> that the core POSIX module withholds,
       implements in Perl or fucked up.

       This module is provided "as is" unless someone volunteers to maintain it.

INCOMPATIBLE PARAMETER CHANGE

       Since version 0.13, the parameter order of pread/pwrite is (count, offset) as with the
       actual system calls instead of (offset, count). Good luck.

FILE DESCRIPTORS AND HANDLES

       Since version 0.05, all I/O functions that take numeric file descriptors also accept Perl
       file or directory handles. "openat()" even returns a handle if you passed it one.

SYSTEM CALL RETURN VALUES

       A system call return value of -1 meaning "error" is mapped to undef.

       A system call return value of 0 meaning "success" is mapped to "0 but true".

       For system calls where 0 does not just mean "success", 0 is returned unchanged. These are
       "open()", "read()", "write()", "readv()", "writev()", "pread()", "pwrite()", "preadv()",
       "pwritev()". "openat()" gets a special treatment in this module, see below.

           •   It really calls fdopen(3).

           •   It expects POSIX  mode strings (e.g. "r", not "<").

           •   It fails mode is not compatible with the flags of fd.

               fdopendir($fh); # or fdopendir(fileno $fh) but the former also works
                               # with handles from opendir() for which fileno does
                               # not work before Perl 5.22

       nrand48
           r = nrand48()

       open
           ret = open(path, oflag[, mode]);

           oflag defaults to O_RDONLY, mode defaults to 0600.

       openat
           ret = openat(fd, path, oflag[, mode]);

           oflag defaults to O_RDONLY, mode defaults to 0600.

           If fd is numeric (i.e. a file descriptor), "openat()" returns a file descriptor. If fd
           is a file or directory handle the return value is also a handle whose type depends on
           the file type of path: If path is a directory, the return value is a directory handle,
           otherwise it's a file handle.

           Returns undef on error.

       posix_fadvise
           ret = posix_fadvise(fd, offset, len, advice);

           advice is one of the "POSIX_FADV_" constants.

           Returns undef on error

       posix_fallocate
           ret = posix_fallocate(fd, offset, len);

       pread
           bytes_read = pread(fd, buf, count, [offset, buf_offset]);

           "pread()" reads count bytes (not characters) of data from the file descriptor fd at
           file offset offset into the scalar buf without changing the file offset. buf will be
           enlarged automatically if necessary.

           offset and buf_offset are set to 0 if omitted or undef.

           "pread()" treats buf just like "sysread()" does: buf_offset may be specified to place
           the read data at that position in buf. If buf_offset is past the end of buf, buf will
           be padded with zeros before appending the data. If buf_offset is negative, it is
           counted from the end of the string. buf will be grown or shrunk so that the last byte
           actually read is the last byte of buf after the read.

           Returns the number of bytes read, 0 at EOF, undef on error.

       preadv
           bytes_read = preadv(fd, buffers, sizes, [offset])

           "preadv()" behaves like "readv()" but adds an optional offset argument, which
           specifies the file position at which the data is to be read. offset is set to 0 if
           omitted or undef.

           The file offset is not changed by this system call. The file referred to by fd must be
           capable of seeking.

       ptsname
           name = ptsname(fd);

       pwrite
           bytes_written = pwrite(fd, buf, [count, offset, buf_offset]);

           pwrite() writes count bytes of data from the scalar buf to the file descriptor fd at
           file offset offset without changing the file offset. The file referenced by fd must be
           capable of seeking.

           If count is omitted or undef, everything from buf_offset up to the end of buf is
           written.

           buf_offset may be specified to write data from that position in buf. If buf_offset is
           negative it is counted from the end of the string.

           offset and buf_offset are set to 0 if omitted or undef.

           Returns the number of bytes written, undef on error.

           On Linux, if a file is opened with O_APPEND, pwrite() appends data to the end of the
           file, regardless of the value of offset (in violation of POSIX).

       pwritev
           bytes_written = pwritev(fd, buffers, [offset])

           "pwritev()" behaves like "writev()" but adds an optional offset argument, which
           specifies the file position at which the data is to be written. offset is set to 0 if
           omitted or undef.

           The file offset is not changed by this system call. The file referred to by fd must be
           capable of seeking.

       random
           r = random();

       read
           bytes_read = read(fd, buf, count);

           Like POSIX::read() but returns 0 at EOF instead of "0 but true".

       readv
           bytes_read = readv(fd, buffers, sizes);

           Example:

             sysopen my $fh, '/tmp/foobar', O_RDWR|O_CREAT|O_TRUNC;
             pwrite($fh, 'foobar', 6, 0);
             readv($fh, my @buf, [4, 0, 4, 4]);
             # -> @buf is ('foob', '', 'ar')

           "readv()" reads from the file descriptor fd into buffers as many strings as there are
           elements in sizes. buffers must be a variable holding an array or an array reference.
           sizes must be an array reference.

           sizes is expected to hold unsigned integers that specify how many bytes are to be read
           into each buffer. A byte count of 0 or undef creates an empty string. sizes is
           processed in array order.

           buffers will be extended if necessary, but it will never be shrunk. If buffers is not
           empty, any existing elements are replaced as long as sufficient data was read from fd.

           If the total byte count of sizes exceeds the number of bytes actually read from fd,
           there may be one partly filled buffer and the rest of sizes is skipped, so you may end
           up with less strings in buffers than there are elements in sizes.

           "readv()" returns the number of bytes read (which may be less than the total bytes in
           sizes) or undef on error.

       readlink
           name = readlink(path);

           Returns undef on error.

       readlinkat
           name = readlinkat(dirfd, path);

           Returns undef on error.

       remainder
           r = remainder(x, y);

       remove
           ret = remove(path);

           Calls the actual C library function "remove()".

           Note that POSIX::remove() fails if path is a symlink to a directory because someone
           "couldn't read the plans right and did a piss-poor job of putting it together" as "(-d
           $_[0]) ? CORE::rmdir($_[0]) : CORE::unlink($_[0])". Quote from Armageddon.

       rename
           ret = rename(old, new);

       renameat
           ret = renameat(olddirfd, oldpath, newdirfd, newpath);

       round
           r = round(x);

       scalbn
           y = scalbn(x, n);

       seed48
           (old_seed1, old_seed2, old_seed3) = seed48(seed1, seed2, seed3);

           ret = setegid(gid);

       seteuid
           ret = seteuid(uid);

       setgid
           ret = setgid(gid);

       setitimer
           (old_int_sec, old_int_usec, old_val_sec, old_val_usec) = setitimer(which, int_sec,
           int_usec, val_sec, val_usec);

           which is one of ITIMER_REAL, ITIMER_VIRTUAL, ITIMER_PROF.

       setpriority
           ret = setpriority(value, which, who);

           which can be one of PRIO_PROCESS, PRIO_PGRP, PRIO_USER, defaults to PRIO_PROCESS.

           Returns true on success, undef on error.

           who defaults to 0.

       setregid
           ret = setregid(rgid, egid);

       setreuid

       srand48
           srand48(seedval);

       srandom
           srandom(seed);

       stat
           (dev, ino, mode, nlink, uid, gid, rdev, size, atim_sec, mtim_sec, ctim_sec, blksize,
           blocks, atim_nsec, mtim_nsec, ctim_nsec) = stat(path);

       strptime
           (sec, min, hour, mday, mon, year, wday, yday, isdst) = strptime(s, format[, sec, min,
           hour, mday, mon, year, wday, yday, isdst]);

           strptime() converts the string s into a broken-down time according to the format
           string format. The time fields may optionally be initialized in whole or in part and
           will be returned as initialized if they are not affected by the format string.
           Unprocessed uninitialized or undef fields are returned as undef.

           Returns an empty list on error.

           In scalar context returns the index of the first byte in s that was not processed or
           the byte length of s if the whole string was consumed or undef on error.

           As strptime() acts on null-terminated strings, strings containing NUL bytes will only
           be processed up to the first NUL byte.

       symlink
           symlink(old, new);

       symlinkat
           ret = symlinkat(old, dirfd, new);

           timerid = timer_create(clockid, signal);

           Returns undef on error.

       timer_delete
           timer_delete(timerid);

           Returns '0 but true' on success, undef on error.

       timer_getoverrun
           count = timer_getoverrun(timerid);

           Returns undef on error.

       timer_gettime
           (interval_sec, interval_nsec, initial_sec, initial_nsec) = timer_gettime(timerid);

           Returns an empty list on error.

       timer_settime
           (old_int_sec, old_int_nsec, old_init_sec, old_init_nsec) = timer_settime(timerid,
           flags, int_sec, int_nsec, [init_sec, init_nsec]);

           flags may be 0 or "TIMER_ABSTIME". If the init values are omitted, they are set to the
           int values.

       truncate
           ret = truncate(path, length);

       trunc
           y = trunc(x);

       unlinkat
           ret = unlinkat(dirfd, path, flags=0);

           flags can be 0 or AT_REMOVEDIR.

       unlink
           ret = unlink(path);

       utimensat
           ret = utimensat(dirfd, path, flags, atime_sec, atime_nsec, mtime_sec, mtime_nsec);

           flags can be 0 or AT_SYMLINK_NOFOLLOW, defaults to 0.

           atime_sec and mtime_sec default to 0. atime_nsec and mtime_nsec default to UTIME_NOW.

       write
           bytes_written = write(fd, buf[, count]);

           Like POSIX::write() but returns 0 instead of "0 but true" if 0 bytes were written, and
           it does not write more bytes than buf contains.

           If count is omitted or undef, it defaults to the length of buf.

       writev
           bytes_written = writev(fd, buffers);

           writev() writes multiple buffers from buffers to the file associated with the file
           descriptor fd. buffers must be an array reference. The buffers are processed in array
           order. Undefined or empty elements are skipped.

           Returns the number of bytes written or undef on error.

       y0  y = y0(x);

           y0() is the Bessel function of the second kind of order 0.

       y1  y = y1(x);

           y1() is the Bessel function of the second kind of order 1.

       yn  y = yn(n, x);

           yn() is the Bessel function of the second kind of order n.
