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			`/*`

Turn struct inject_data.rval into an index Add one level of indirection to decrease the size of struct inject_data as hundreds of these structures are created for each process when injection mechanism is activated. * retval.h: New file. * retval.c: Likewise. * Makefile.am (strace_SOURCES): Add them. * defs.h (struct inject_data): Replace rval field with rval_idx. * filter_qualify.c: Include "retval.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_RETVAL_H`
