       toupper - transliterate lower-case characters to	upper-case

SYNOPSIS
       #include	<ctype.h>

       int toupper(int c);

DESCRIPTION
       The  toupper()  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 toupper() represents	a lower-case letter, and there	exists
       a  corresponding	upper-case letter (as defined by character type	infor-
       mation in the program locale category LC_CTYPE),	  the  result  is  the
       corresponding  upper-case letter. All other arguments in	the domain are
       returned	unchanged.

RETURN VALUES
       On successful completion, toupper() returns the upper-case letter  cor-
       responding to the argument passed.

ERRORS
       No errors are defined.
