### strnset - strset -- Set Characters in String

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;

       /****************************************************************************
          The output should be:

          This is the string: abcdefghi
          This is the string after strnset: xxxxefghi
          This is the string after strset: kkkkkkkkk
