NAME

       re_comp, re_exec - BSD regex functions

SYNOPSIS

       #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.
