INFORMIX-ESQL/C Programmer's Manual ESQL/C Function Library

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

void rdownshift(s)

	char  *s;

 



s  

is a pointer to a null-terminated string. 

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-z) and uppercase (A-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 Guide to GLS Functionality.

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

/*
* rdownshift.ec *

The following program uses rdownshift() on a string containing alpha,
numeric and punctuation characters.

#include <stdio.h>

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

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

printf("\tInput string...: [%s]\n", string);
rdownshift(string);
printf("\tAfter downshift: [%s]\n", string);

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

RDOWNSHIFT Sample ESQL Program running.
