Syntax

#include <string.h>  /* also in <memory.h> */
void *memset(void *dest, int c, size_t count);

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
   ****************************************************************************/
