| * Name: pthread_kill |
| * |
| * Description: |
| * The pthread_kill() system call can be used to send any signal to a |
| * thread. See nxsig_kill() for further information as this is just a |
| * simple wrapper around the nxsig_kill() function. |
| * |
| * Input 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. |
| * |
| * Returned 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. |
