This interpretation request is for the following assertions:
/tset/XPG4.os/ipc/semctl/T.semctl 17 Unresolved
/tset/XPG4.os/ipc/semctl/T.semctl 18 Unresolved
/tset/XPG4.os/ipc/semop/T.semop 4 Unresolved

/tset/XPG4.os/ipc/semop/T.semop 15 Unresolved
These tests define an mbuf structure like the following:
private struct mbuf {
int mtype;
char mtext[MSGSZ];
};
This structure is then used in a call to msgsnd() or msgrcv() as follows:
if (msgsnd(msgid, (void *)&mbuf, MSGSZ, IPC_NOWAIT) == SYSERROR) { \
or
if (msgrcv(msgid, (void *)&mbuf, MSGSZ, 0, IPC_NOWAIT) == SYSERROR) { \
However, on page 551 of the XPG5 XSH, it states the followwing:
"DESCRIPTION The msgrcv() function ....
The argument msgp points to a user-defined buffer that must
contain first a field of long int that will specify the type of
the message, and then a data portion that will hold the data
bytes of the message. ....."
and on page 554, msgsnd()
" The structure member mtype is a non-zero positive type long int
that can be used by the receiving process for message selection."
The same problem exists in the semop source.Test Output
************************************************************************
/tset/XPG4.os/ipc/semctl/T.semctl 17 Unresolved
Test Description:
When the process has read permission, a call to
semctl(semid,semnum,GETNCNT,arg) returns the number of processes which
are waiting for the value associated with the semaphore referenced by
semid and semnum to increase from its current value.
Test Information:
msgsnd() unexpectedly failed, error: EINVAL
************************************************************************
************************************************************************
/tset/XPG4.os/ipc/semctl/T.semctl 18 Unresolved
Test Description:
When the process has read permission, a call to
semctl(semid,semnum,GETZCNT,arg) returns the number of processes which
are waiting for the value associated with the semaphore referenced by
semid and semnum to become zero.
Test Information:
msgsnd() unexpectedly failed, error: EINVAL
************************************************************************
************************************************************************
/tset/XPG4.os/ipc/semop/T.semop 4 Unresolved
Test Description:
When the calling process has alter permission for the semaphore set
and sem_op is negative and semval is less than the absolute value of
sem_op, and the IPC_NOWAIT flag is not set in sem_flag then a
successful call to semop(semid,sops,nsops) increments the semncnt
associated with the specified semaphore and suspends the calling
process awaiting a change in the semval associated with the specified
semaphore.
Test Information:
msgsnd() unexpectedly failed, error: 22 (EINVAL)
************************************************************************
************************************************************************
/tset/XPG4.os/ipc/semop/T.semop 5 Unresolved
Test Description:
When the process has been suspended awaiting an increase in a
semaphore value and the value of the semaphore semval is changed such
that it becomes greater than or equal to the absolute value of the
sem_op associated with the call to semop(semid,sops,nsops) which
caused the process to be suspended, then the value of semncnt
associated with the semaphore is decremented and the absolute value of
sem_op is subtracted from semval, and the absolute value of sem_op is
added to the semadj value if the SEM_UNDO flag is set in sem_flg and
the suspended call shall return zero.
Test Information:
msgsnd() unexpectedly failed, error: 22 (EINVAL)
************************************************************************
************************************************************************
/tset/XPG4.os/ipc/semop/T.semop 7 Unresolved
Test Description:
When the process has been suspended awaiting an increase in a
semaphore value and the calling process receives a signal that is to
be caught, then the call to semop(semid,sops,nsops) decrements the
semncnt value associated with the semaphore, returns -1 and sets
'errno' to EINTR.
Test Information:
msgsnd() unexpectedly failed, error: 22 (EINVAL)
************************************************************************
************************************************************************
/tset/XPG4.os/ipc/semop/T.semop 12 Unresolved
Test Description:
When the calling process has read permission for the semaphore set and
sem_op is zero and semval is not zero, and the IPC_NOWAIT flag is not
set in sem_flag than a successful call to semop(semid,sops,nsops)
increments the semzcnt associated with the specified semaphore and
suspends the calling process awaiting a change in the semval
associated with the specified semaphore.
Test Information:
msgsnd() unexpectedly failed, error: 22 (EINVAL)
************************************************************************
************************************************************************
/tset/XPG4.os/ipc/semop/T.semop 13 Unresolved
Test Description:
When the process has been suspended awaiting zeroing of a semaphore
value and the value of the semaphore's semval is changed such that it
becomes zero, then the value of semzcnt associated with the semaphore
is decremented and the suspended call to semop(semid,sops,nsops)
returns zero.
Test Information:
msgsnd() unexpectedly failed, error: 22 (EINVAL)
************************************************************************

/tset/XPG4.os/ipc/semop/T.semop 15 Unresolved
Test Description:
When the process has been suspended awaiting zeroing of a semaphore
value and the calling process receives a signal that is to be caught,
then the call to semop(semid,sops,nsops) decrements the semzcnt value
associated with the semaphore, returns -1 and sets errno to EINTR.
Test Information:
msgsnd() unexpectedly failed, error: 22 (EINVAL)
