Synopsis:

#include <string.h>

void* memset( void* dst,
              int c,
              size_t length );

Arguments:

dst

Description:

The memset() function fills length bytes starting at dst with the value c.

Returns:

A pointer to the destination buffer (that is, the value of dst).

Examples:

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

int main( void )
{
    char buffer[80];

    memset( buffer, '=', 80 );
    buffer[79] = '\0';
    
    puts( buffer );
    
    return EXIT_SUCCESS;
}
