RE_COMP(3) Linux Programmer's Manual RE_COMP(3)
re_comp, re_exec - BSD regex functions
#define _REGEX_RE_COMP
#include <sys/types.h>
#include <regex.h>
char *re_comp(const char *regex);
int re_exec(const char *string);
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.
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.
For an explanation of the terms used in this section, see
attributes(7).

These functions are obsolete; the functions documented in regcomp(3)
should be used instead.
