| The resulting set shall be the union of the current set and the signal |
| set pointed to by set, if the value of the argument how is SIG_BLOCK. |
| |
| Steps: |
| 1. Have main create a new thread and wait for its termination. |
| 2. Inside the new thread, set up the signal mask such that it contains |
| only SIGABRT. |
| 3. Also inside the new thread, using the SIG_BLOCK as the value to |
| pthread_sigmask's first parameter, add SIGALRM. Now both signals |
| should be in the signal mask of the new thread. |
| 4. Raise both signals make sure that the handler associated with these |
| signals wasn't executed. |
| 5. Also make sure that both signals are pending. |
| 6. Pass one of three return codes to the main() function: |
| - A value of -1 if one of the two signals wasn't found pending or |
| causes the handler to be executed. |
| - A value of 0 if both signals were infact pending and the handler |
| wasn't executed. |
| - A value of 1 incase of any UNRESOLVED situation such as an |
| unexpected function failure. |
