* This sample test aims to check the following assertion:
|
||||||
|
*
|
||||||
|
* The child process is created with no pending signal
|
||||||
|
|
||||||
|
* The steps are:
|
||||||
|
* -> block SIGUSR1 and SIGUSR2
|
||||||
|
* -> send those signals and wait they are pending
|
||||||
|
* -> fork
|
||||||
|
* -> check the signals are blocked but not pending in the new process.
|
||||||
|
|
||||||
|
* The test fails if the signals are pending or if
|
||||||
|
* they are not blocked (this counters assertion 2).
