NAME
       FFI::C::PosixFile - Perl interface to C File pointer with POSIX extensions


VERSION
       version 0.15


SYNOPSIS
        use FFI::C::PosixFile;

        my $stdout = FFI::C::PosixFile->fdopen(1, "w");
        say $stdout->fileno;  # prints 1


DESCRIPTION
       This is a subclass of FFI::C::File which adds a couple of useful POSIX extensions that may not be
       available on non-POSIX systems.  Trying to create an instance of this class will fail on platforms that
       do not support the extensions.


CONSTRUCTOR
   fopen
        my $file = FFI::C::PosixFile->fopen($filename, $mode);

       Opens the file with the given mode.  See your standard library C documentation for the exact format of
       $mode.

   new
        my $file = FFI::C::PosixFile->new($ptr);

       Create a new File instance object from the opaque pointer.  Note that it isn't possible to do any error
       checking on the type, so make sure that the pointer you are providing really is a C file pointer.

   fdopen
        my $file = FFI::C::PosixFile->fdopen($fd, $mode);

       Create a new File instance from a POSIX file descriptor.


METHODS
   fileno
        my $fd = $file->fileno;

       Returns the POSIX file descriptor for the file pointer.
