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.
