Format
#include <string.h> char *strnset(char *string, int c, size_t n); char *strset(char *string, int c);
Language Level: Extension
strnset sets, at most, the first n characters of string
to c (converted to a char). If n is greater
than the length of string, the length of string
is used in place of n. strset sets all characters of string,
except the ending null character (\0), to c (converted
to a char).
For both functions, the string is a null-terminated string.
Return Value
Both strset and strnset return a pointer to the altered string.
There is no error return value.
Example
In this example, strnset sets not more than four
characters of a string to the character 'x'. Then the strset
function changes any non-null characters of the string to the
character 'k'.
#include <stdio.h> #include <string.h>
int main(void)
{
char str[] = "abcdefghi";
printf("This is the string: %s\n", str);
printf("This is the string after strnset: %s\n", strnset((char*)str, 'x', 4));
printf("This is the string after strset: %s\n", strset((char*)str, 'k'));
return 0;
