Add copyright headers to some files that lack them We do our best to keep copyright headers up to date, yet git history provides better information on this subject and is more accurate than copyright headers. 2018-12-25 02:46:43 +03:00			`/*`

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`
Fix preprocessor indentation Indent the C preprocessor directives to reflect their nesting using the following script: $ cppi -l $(git grep -El '^[[:space:]]#[[:space:]](if\|ifdef\|ifndef\|elif\|else\|endif\|define\|pragma)[[:space:]]' \|grep -v '\.sh$') \|while read f; do cppi < "$f" > "$f".cppi; mv "$f".cppi "$f" done 2018-12-30 18:35:21 +03:00			`# define 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 03:02:41 +03:00
