Syntax
#include <string.h> /* also in <memory.h> */ void *memset(void *dest, int c, size_t count);Description
memset sets the first count bytes of dest to the value c. The value of c is converted to an unsigned char.
memset returns a pointer to dest.
This example sets 10 bytes of the buffer to A and the next 10 bytes to B.
#include <string.h>
#include <stdio.h>
#define BUF_SIZE 20
int main(void)
{
char buffer[BUF_SIZE+1];
char *string;
memset(buffer, 0, sizeof(buffer));
string = memset(buffer, 'A', 10);
printf("\nBuffer contents: %s\n", string);
memset(buffer+10, 'B', 10);
printf("\nBuffer contents: %s\n", buffer);
return 0;
/****************************************************************************
The output should be:
Buffer contents: AAAAAAAAAA
Buffer contents: AAAAAAAAAABBBBBBBBBB
