memcpy - copy memory area SYNOPSIS #include <string.h> void *memcpy(void *dest, const void *src, size_t n); DESCRIPTION The memcpy() function copies n bytes from memory area src to memory area dest. The memory areas must not overlap. Use memmove(3) if the memory areas do overlap. memcpy_s copies count bytes from src to dest; wmemcpy_s copies count wide characters (two bytes). If the source and destination overlap, the behavior of memcpy_s is undefined. Use memmove_s to handle overlapping regions. These functions validate their parameters. Pixman.
