* Name: 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: |
|
* |
