memset

---

Defined in string.h

void *memset( void *s, int c, size_t n);

The memset() function initializes the n bytes of the memory area pointed by s with to the str argument.

Parameters

s : pointer to the block of memory to fill.

c : the value to set .

n : number of bytes to set.

#include <stdio.h>
#include <string.h>

int main ( int argc, char* argv[]) 
{
	char s[50];
	memset( s, 0, sizeof(s));

	return EXIT_SUCCESS;
}

The above program, set the block of memory to 0 by using memset.

#include <stdio.h>
#include <string.h>

typedef struct myData
{
	char str[50];
	int i;
} MyData;

int main ( int argc, char* argv[]) 
{
	MyData mMyData;
	memset( &mMyData, 0, sizeof(MyData));

	return EXIT_SUCCESS;
}

The above program, initializes the struct with memset.
