Synopsis:
    #include <string.h>
    char *strupr( char *s );
    char *_strupr( char *s );
    char __far *_fstrupr( char __far *s );
    #include <wchar.h>
    wchar_t *_wcsupr( wchar_t *s );
    #include <mbstring.h>
    unsigned char *_mbsupr( unsigned char *s );
    unsigned char __far *_fmbsupr( unsigned char __far *s );

Description:
    The strupr function replaces the string s with uppercase characters by
    invoking the  toupper function for each character in the string.

    The _strupr function is identical to strupr.  Use _strupr for ANSI/ISO
    naming conventions.

    The _fstrupr function is a data model independent form of the strupr
    function.  It accepts far pointer arguments and returns a far pointer.
     It is most useful in mixed memory model applications.

    The _wcsupr function is a wide-character version of strupr that operates
    with wide-character strings.

    The _mbsupr function is a multibyte character version of strupr that
    operates with multibyte character strings.

Returns:
    The address of the original string s is returned.

Example:
    #include <stdio.h>
    #include <string.h>

    char source[] = { "A mixed-case STRING" };

    void main()
      {
        printf( "%s\n", source );
        printf( "%s\n", strupr( source ) );
        printf( "%s\n", source );
      }

    produces the following:

    A mixed-case STRING
    A MIXED-CASE STRING
    A MIXED-CASE STRING
