NAME
       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.
