hey, thanks for your reply
ok i tried to create a STC, but i'm don't really know ipc and shared
mem.. anyway i traced down the part, which cause trouble
(init code, called before the fork occours)
if ((shmid = shmget(IPC_PRIVATE, allocationSize, IPC_CREAT | 0777)) < 0)
FATAL("problems shmget'ing\n");
//if ((shmid = shmget(IPC_PRIVATE, allocationSize, IPC_CREAT | 0600)) <
0) FATAL("problems shmget'ing\n");
if (!(playerData_pd = shmat(shmid, NULL, 0))) FATAL("problems
shmat'ing\n");
if (shmctl(shmid, IPC_RMID, NULL) < 0) FATAL("problems shmctl'ing\n");
when i comment out
if (shmctl(shmid, IPC_RMID, NULL) < 0) FATAL("problems
shmctl'ing\n");
mpd works like a charm.
IPC_RMID is used to mark the segment as destroyed. It
will actually be destroyed after the last
detach. (I.e., when the shm_nattch member of
the associated structure shmid_ds is zero.)
The user must be the owner, creator, or the
super-user.
can someone explain me, what i just did? I also tried to change the
shmget rights from 0600 to 0777.
thanks in advance
michu
