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, U.S. English, rupshift() uses the ASCII lowercase (a-z) and uppercase (A-Z) letters.

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