Hello everyone,
in order to try to use mmap() to perform IPC I am writing a test program like
this :
int main(char **argv, int argn)
{
char *addr;
int fd;
if ((fd = open(FILENAME, O_RDWR) == -1)) {
perror("open:");
exit(1);
}
addr = mmap(NULL, SIZE, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);
if (addr == MAP_FAILED) {
printf("mmap() : %p %s", addr, strerror(errno));
exit(1);
}
close(fd);
....
I am running under
Linux crunchbang 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux
My problem is that everytime I have got an "No such device" error which I don't
fully get, could a problem of my platoform
or am I simply doing something wrong ?
Thanks all,
Pietro
