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;
 }
