memcpy
Copies n characters from the object pointed to by s2 into the object pointed to by s1. If the
two regions overlap, the behavior is undefined.
Synopsis
#include
void *memcpy(void *s1, const void *s2, size_t n);
Returns
The value of s1.
Example
char s1[10];
char s2[10] = "COMPASS";
memcpy(s1, s2, 8);
memmove
Moves n characters from the object pointed to by s2 into the object pointed to by s1.
Copying between objects that overlap takes place correctly.
Synopsis
#include
void *memmove(void *s1, const void *s2, size_t n);
Returns
The value of s1.
Example
char s1[10];
char s2[]="COMPASS";
memmove(s1, s2, 8*sizeof(char));
memset
Copies the value of c (converted to an
unsigned char
) into each of the first n characters
of the object pointed to by s.
