Description
#include <stdlib.h>
#include <sys/types.h>
#include <sys/mman.h>
#include <unistd.h>
int main(int argc, char *argv[]) {
char *c = mmap(NULL, 4096, PROT_READ | PROT_WRITE, MAP_PRIVATE |
MAP_ANON, -1, 16);
return printf("%x \n", c);
}
gets an address of xxxxx010. mmap is supposed to fail with EINVAL given an
offset and MAP_ANON.
