re_comp, re_exec - BSD regex functions
char *re_comp(char *regex);
int re_exec(char *string);
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.
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.
