strlwr
Replaces each character of a string with its lowercase equivalent
#include <string.h>
char *strlwr (
char *str);
The address of the converted string is returned.
strlwr replaces the string str with lowercase characters by invoking the tolower function for each character in the string.
#include <string.h>
#include <stdio.h>
char source[ ] = { "A mixed-case STRING" };
main ()
{
printf ("%s\n", source);
printf ("%s\n", strlwr (source) );
printf ("%s\n", source);
}
produces the following:
A mixed-case STRING a mixed-case string a mixed-case string
