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.
