The rdownshift() function

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

Syntax

void rdownshift(s)
   char *s;
s
A pointer to a null-terminated string.

Usage

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

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