NAME
POSIX::2008 - Perl interface to POSIX.1-2008
SYNOPSIS
use POSIX qw(:fcntl_h);
use POSIX::2008;
my $dd = POSIX::2008::open('/tmp/');
my $fd = POSIX::2008::openat($dd, 'foobar', O_RDWR|O_CREAT);
POSIX::2008::pwrite($fd, 'fuckyounsa', 50);
DESCRIPTION
POSIX::2008 contains many of the interfaces specified by POSIX.1-2008 that the core POSIX module
withholds, implements in Perl or fucked up.
This module is provided "as is" unless someone volunteers to maintain it.

pread() reads nbytes 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.
buf_offset may be specified to store the data at that position in buf. Defaults to 0. 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.
Returns the number of bytes read, 0 at EOF, undef on error.
Note that pread() deals with bytes not characters.
ptsname
name = ptsname(fd);
pwrite
bytes_written = pwrite(fd, buf, offset[, nbytes, buf_offset]);
pwrite() writes 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.
nbytes may be specified to write only that much bytes. If not specified 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. Defaults to 0. If buf_offset is
negative it is counted from the end of the string.
Returns the number of bytes written, undef on error.
Note that pwrite() deals with bytes not characters.

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.
