Dear Managers,
I have few problems (twice a year) with the semop system call.
A program which usually works fine failed on a semaphore operation.
The errno error code was either no set (0) or set to a strange value
(not documented). As state in the semop manual page, the program
considers that the semop operation succeeds if it returns a zero value.
But I wonder if the semop system call may return a postive value on
success or if there is a bug in the semop implementation.
I would be pleased if one could send me the kernel source code of the
semop system call. Up to now, I have no response from Digital support.
(I am using DU 3.2C, but I had the same problem on Ultrix 4.3.1, but
never on AIX, HPUX, Solaris, LynxOS ... this is why I consider that
my program is correctly written)
Thanks a lot.
Laurent.
