RedHat 9 (Linux i386) - man page for re_comp (redhat section 3)

re_comp(3)				       GNU				       re_comp(3)

NAME
       re_comp, re_exec - BSD regex functions

SYNOPSIS
       #include <sys/types.h>
       #include <regex.h>

       char *re_comp(char *regex);
       int re_exec(char *string);

DESCRIPTION
       re_comp	is  used  to  compile the null-terminated regular expression pointed to by regex.
       The compiled pattern occupies a static area, the pattern buffer, which is  overwritten  by
       subsequent  use	of  re_comp.  If regex is NULL, no operation is performed and the pattern
       buffer's contents are not altered.

       re_exec is used to assess whether the null-terminated string pointed to by string  matches
       the previously compiled regex.

RETURN VALUE
       re_comp	returns NULL on successful compilation of regex otherwise it returns a pointer to
       an appropriate error message.

       re_exec returns 1 for a successful match, zero for failure.

CONFORMING TO
       BSD 4.3
