+.SH DESCRIPTION
+.BR re_comp ()
+is used to compile the null-terminated regular expression pointed to by
+.IR regex .
+The compiled pattern occupies a static area, the pattern buffer,
+which is overwritten by subsequent use of
+.BR re_comp ().
+If
+.I regex
+is NULL,
+no operation is performed and the pattern buffer's contents are not
+altered.
+.P
+.BR re_exec ()
+is used to assess whether the null-terminated string pointed to by
+.I string
+matches the previously compiled
+.IR regex .
+.SH RETURN VALUE
+.BR re_comp ()
+returns NULL on successful compilation of
+.I regex
+otherwise it returns a pointer to an appropriate error message.
+.P
+.BR re_exec ()
+returns 1 for a successful match, zero for failure.
