5 Fcntl - load the C Fcntl.h defines
13 This module is just a translation of the C F<fnctl.h> file.
14 Unlike the old mechanism of requiring a translated F<fnctl.ph>
15 file, this uses the B<h2xs> program (see the Perl source distribution)
16 and your native C compiler. This means that it has a
17 far more likely chance of getting the numbers right.
21 Only C<#define> symbols get translated; you must still correctly
22 pack up your own arguments to pass as args for locking functions, etc.
