=head1 NAME
Fcntl - load the C Fcntl.h defines
=head1 SYNOPSIS
use Fcntl;
use Fcntl qw(:DEFAULT :flock);
=head1 DESCRIPTION
This module is just a translation of the C F file.
Unlike the old mechanism of requiring a translated F
file, this uses the B program (see the Perl source distribution)
and your native C compiler. This means that it has a
far more likely chance of getting the numbers right.
=head1 NOTE
Only C<#define> symbols get translated; you must still correctly
pack up your own arguments to pass as args for locking functions, etc.
=head1 EXPORTED SYMBOLS
By default your system's F_* and O_* constants (eg, F_DUPFD and
O_CREAT) and the FD_CLOEXEC constant are exported into your namespace.
You can request that the flock() constants (LOCK_SH, LOCK_EX, LOCK_NB
and LOCK_UN) be provided by using the tag C<:flock>. See L.
You can request that the old constants (FAPPEND, FASYNC, FCREAT,
FDEFER, FEXCL, FNDELAY, FNONBLOCK, FSYNC, FTRUNC) be provided for
compatibility reasons by using the tag C<:Fcompat>. For new
applications the newer versions of these constants are suggested
(O_APPEND, O_ASYNC, O_CREAT, O_DEFER, O_EXCL, O_NDELAY, O_NONBLOCK,
O_SYNC, O_TRUNC).
For ease of use also the SEEK_* constants (for seek() and sysseek(),
e.g. SEEK_END) and the S_I* constants (for chmod() and stat()) are
available for import. They can be imported either separately or using
the tags C<:seek> and C<:mode>.
Please refer to your native fcntl(2), open(2), fseek(3), lseek(2)
(equal to Perl's seek() and sysseek(), respectively), and chmod(2)
documentation to see what constants are implemented in your system.
See L to learn about the uses of the O_* constants
with sysopen().
See L and L about the SEEK_* constants.
See L about the S_I* constants.
