From my application : the calling semctl as follow:
method name()
{
int cntr=0
union semun semopts;
semopts.val=1
semctl ( *sid, cntr, SETVAL, semopts);
}

Am i calling the semctl in correct format? If so why am i getting the error?

If i look into sem.cc it is defined as follows:

semctl (int semid, int semnum, int cmd, ...)

With Regards,
Neo.
