RE_COMP(3)                                          Linux Programmer's Manual                                         RE_COMP(3)



NAME
       re_comp, re_exec - BSD regex functions

SYNOPSIS
       #define _REGEX_RE_COMP
       #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
       4.3BSD.

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