-semaphore_destroy
Function - Destroy a semaphore.
SYNOPSIS
kern_return_t semaphore_destroy
(task_t task,
semaphore_t semaphore);
PARAMETERS
- task
-
[in task port] The task associated with the target semaphore.
- semaphore
-
[in send right] The port naming the semaphore to be destroyed.
DESCRIPTION
The semaphore_destroy function destroys a semaphore.
All send rights
naming the semaphore become dead names. Threads waiting on the
semaphore become unblocked with the return from the
semaphore_wait
call indicating that the semaphore was destroyed. A call to
semaphore_destroy succeeds only if the semaphore is associated
with the specified task.
RETURN VALUES
- KERN_INVALID_ARGUMENT
-
Either, or both, the task or semaphore arguments were invalid.
- KERN_INVALID_RIGHT
-
The specified task does not own the specified semaphore.
- KERN_TERMINATED
-
The specified semaphore was previously destroyed.
- KERN_SUCCESS
-
The semaphore was destroyed.
