re_comp

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.

ATTRIBUTES

   Multithreading (see pthreads(7))
       The re_comp() and re_exec() functions are not thread-safe.

CONFORMING TO

       4.3BSD.

NOTES

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

SEE ALSO

       regcomp(3), regex(7), GNU regex manual
