SYNOPSIS
#include <string.h>
void *memset(
void *s,
int c,
size_t n);
PARAMETERS
s Points to the location of a string.
c Specifies a byte for which c is the target of the copy.
n Specifies the number of bytes to copy.
DESCRIPTION
The memset() function operates on strings in memory areas. A memory area is a group of con-
tiguous bytes bound by a count and not terminated by a null character. This memory function
does not check for overflow of the receiving memory area.
The memset() function copies the value of the byte specified by the c parameter, which is con-
verted to an unsigned char, into each of the first n locations of the string pointed to by the s
parameter.
RETURN VALUES
The memset() function returns the string pointed to by the s parameter.
