5					Fcntl - load the C Fcntl.h defines

7					=head1 SYNOPSIS
8
9					use Fcntl;
10					use Fcntl qw(:DEFAULT :flock);
11
12					=head1 DESCRIPTION
13
14					This module is just a translation of the C F<fcntl.h> file.
15					Unlike the old mechanism of requiring a translated F<fcntl.ph>
16					file, this uses the B<h2xs> program (see the Perl source distribution)
17					and your native C compiler. This means that it has a
18					far more likely chance of getting the numbers right.
19
20					=head1 NOTE
21
22					Only C<#define> symbols get translated; you must still correctly
23					pack up your own arguments to pass as args for locking functions, etc.
24
25					=head1 EXPORTED SYMBOLS
26
27					By default your system's F_* and O_* constants (eg, F_DUPFD and
28					O_CREAT) and the FD_CLOEXEC constant are exported into your namespace.
29
30					You can request that the flock() constants (LOCK_SH, LOCK_EX, LOCK_NB
31					and LOCK_UN) be provided by using the tag C<:flock>. See L<Exporter>.
32
33					You can request that the old constants (FAPPEND, FASYNC, FCREAT,
34					FDEFER, FEXCL, FNDELAY, FNONBLOCK, FSYNC, FTRUNC) be provided for
35					compatibility reasons by using the tag C<:Fcompat>. For new
36					applications the newer versions of these constants are suggested
37					(O_APPEND, O_ASYNC, O_CREAT, O_DEFER, O_EXCL, O_NDELAY, O_NONBLOCK,
38					O_SYNC, O_TRUNC).
39
40					For ease of use also the SEEK_* constants (for seek() and sysseek(),
41					e.g. SEEK_END) and the S_I* constants (for chmod() and stat()) are
42					available for import. They can be imported either separately or using
43					the tags C<:seek> and C<:mode>.
44
45					Please refer to your native fcntl(2), open(2), fseek(3), lseek(2)
46					(equal to Perl's seek() and sysseek(), respectively), and chmod(2)
47					documentation to see what constants are implemented in your system.
48
49					See L<perlopentut> to learn about the uses of the O_* constants
50					with sysopen().
51
52					See L<perlfunc/seek> and L<perlfunc/sysseek> about the SEEK_* constants.
53
54					See L<perlfunc/stat> about the S_I* constants.
