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 functions 
		locate the terminating \0'.

     The strrchr() function is identical to strchr(),
	except it locates the last occur-
     rence 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.
