NAME memfrob – frobnicate (encrypt) a memory area SYNOPSIS #define _GNU_SOURCE /* See feature_test_macros(7) */ #include <string.h> void *memfrob(void *s, size_t n); DESCRIPTION The memfrob() function encrypts the first n bytes of the memory area s by exclusive-ORing each character with the number 42. The effect can be reversed by using memfrob() on the encrypted…

NAME 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. RETURN VALUE The memcpy() function returns a pointer to…
