* Function: pthread_kill
|
|
*
|
|
* Description:
|
|
* The pthread_kill() system call can be used to send any
|
|
* signal to a thread. See kill() for further information
|
|
* as this is just a simple wrapper around the kill()
|
|
* function.
|
|
*
|
|
* Parameters:
|
|
* thread - The id of the thread to receive the signal. Only
|
|
* positive, non-zero values of 'thread' are supported.
|
|
* signo - The signal number to send. If 'signo' is zero,
|
|
* no signal is sent, but all error checking is performed.
|
|
*
|
|
* Return Value:
|
|
* On success the signal was send and zero is returned.
|
|
* On error one of the following error numbers is returned.
|
|
*
|
|
* EINVAL An invalid signal was specified.
|
|
* EPERM The thread does not have permission to send the
|
|
* signal to the target thread.
|
|
* ESRCH No thread could be found corresponding to that
|
|
* specified by the given thread ID
|
|
* ENOSYS Do not support sending signals to process groups.
|
|
*
|
|
* Assumptions:
