Unify usage of #include guards This commit is an attempt to unify usage of include guards (in top-level headers, at least). As a side note, different files with .h extension have different semantics: for example, printargs.h is included multiple times in order to generate slightly varying code depending on values of macro definitions - maybe it's better to change extension of such files to something like .inc. * defs.h: Add #include guard. * flock.h: Likewise. * ipc_defs.h: Likewise. * mpers_type.h: Likewise. * printsiginfo.h: Likewise. * ptrace.h: Likewise. * regs.h: Likewise. * seccomp_fprog.h: Likewise. * gcc_compat.h: Rename the macro used for #include guard. * msghdr.h: Likewise. * sigevent.h: Likewise. * kernel_types.h: Comment the trailing part of #include guard. * xlat.h: Add missing macro definition for #include guard. 2016-08-07 06:44:19 +03:00			`#ifndef STRACE_MSGHDR_H`

net.c: move fallback definition of struct mmsghdr to a separate file. * msghdr.h: New file. * Makefile.am (strace_SOURCES): Add it. * net.c: Include it. Move fallback definition of struct mmsghdr there. * tests/mmsg.c: Include "msghdr.h". Remove fallback definition of struct mmsghdr. 2016-06-27 00:02:41 +00:00

msghdr.c: move all mmsghdr parsers to a separate file * msghdr.h (print_struct_msghdr): New prototype. * msghdr.c (print_msghdr): Rename to print_struct_msghdr, remove static qualifier, all callers changed.
