Prototype
char *strnset(char *s, int ch, size_t n);
wchar_t *_wcsnset(wchar_t *s, wchar_t ch, size_t n);
unsigned char *_mbsnset(unsigned char *s, unsigned int ch, size_t n);
Description
Sets a specified number of characters in a string to a given character.
strnset copies the character ch into the first n bytes of the string s. If n > strlen(s), then strlen(s) replaces n. It stops when n characters have been set, or when a null character is found.
Return Value
Each of these functions return s.
Example
#include <stdio.h>
#include <string.h>
int main(void)
{
char *string = "abcdefghijklmnopqrstuvwxyz";
char letter = 'x';
printf("string before strnset: %s\n", string);
strnset(string, letter, 13);
printf("string after strnset: %s\n", string);
return 0;
}
