NAME
       tolower - transliterate upper-case characters to	lower-case

SYNOPSIS
       #include	<ctype.h>

       int tolower(int c);

DESCRIPTION
       The  tolower()  function	has as a domain	a type int, the	value of which
       is representable	as an unsigned char or the value of EOF. If the	 argu-
       ment  has  any  other value, the	argument is returned unchanged.	If the
       argument	of tolower() represents	an upper-case letter, and there	exists
       a  corresponding	lower-case letter (as defined by character type	infor-
       mation in the program locale category LC_CTYPE),	  the  result  is  the
       corresponding  lower-case letter. All other arguments in	the domain are
       returned	unchanged.

RETURN VALUES
       On successful completion, tolower() returns the lower-case letter  cor-
       responding  to  the argument passed. Otherwise, it returns the argument
       unchanged.

ERRORS
       No errors are defined.
