** DESCRIPTION
** The strchr() function locates the first occurrence of c (converted to a
** char) in the string pointed to by s.  The terminating null character is
** considered to be part of the string; therefore if c is `\0', the func-
** tions locate the terminating `\0'.
**
** The strrchr() function is identical to strchr(), except it locates the
** last occurrence of c.
**
** RETURN VALUES
** The functions strchr() and strrchr() return a pointer to the located
** character, or NULL if the character does not appear in the string.
