Sorry, my mistake. Acutally, I was trying to debug this:
On linux, I don't understand why:
f = open ('/dev/eos', 'rw')
m = mmap.mmap(f.fileno(), 1000000, prot=mmap.PROT_READ|mmap.PROT_WRITE,
flags=mmap.MAP_SHARED)
gives 'permission denied', but this c++ code works:
#include <sys/mman.h>
#include <fcntl.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <iostream>
int main() {
int fd = open ("/dev/eos", O_RDWR);
void* m = mmap (NULL, 1000000, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0);
std::cout << m << '\n';
}
