Hi!
somebody can give me a light?
I have the following piece of code
#include <sys/ipc.h>
...
shmid = shmget(IPC_PRIVATE, len, SHM_R | SHM_W);
if (shmid == -1) {
printf("can't get shared memory\n");
exit(1);
}
state = (struct state *)shmat(shmid, 0, 0);
if (!state || state == (struct state *)-1) {
printf("can't attach to shared memory\n");
exit(1);
}
shmctl(shmid, IPC_RMID, 0);
the compiler gives me warning of implicit declaration
at the end, these 3 functions doesn't link against libroot
Why?
Atenciosamente,
Michael Vinícius de Oliveira
