The rupshift() function

The rupshift() function changes all the characters within a null-terminated string to uppercase characters.

Syntax

void rupshift(s)
   char *s;

s: A pointer to a null-terminated string.

Usage

The rupshift() function refers to the current locale to determine uppercase and lowercase letters. For the default locale, US English, rupshift() uses the ASCII lowercase (a-z) and uppercase (A-Z) letters.

If you use a nondefault locale, rupshift() uses the lowercase and uppercase letters that the locale defines. For more information, see the HCL Informix GLS User's Guide.

Example

This sample program is in the rupshift.ec file in the demo directory.

/*
   * rupshift.ec *

   The following program displays the result of rupshift() on a string
   of numbers, letters and punctuation.

#include <stdio.h>

main()
{
    static char string[] = "123abcdefghijkl;.";

    printf("RUPSHIFT Sample ESQL Program running.\n\n");

    printf("\tInput  string: %s\n", string);
    rupshift(string);
    printf("\tAfter upshift: %s\n", string);    /* Result */

    printf("\nRUPSHIFT Sample Program over.\n\n");
}

Output
