|
|
* Second attempt should fail (ESRCH).

|
|
* Environment:
|
|
* -
|
|
*
|
|
* Input:
|
|
* - None.
|
|
*
|
|
* Output:
|
|
* - File name, Line number, and failed expression on failure.
|
|
* - No output on success.

|
*
|
|
* Assumptions:
|
|
* - have working pthread_create, pthread_self, pthread_mutex_lock/unlock

|
|
*
|
|
* Fail Criteria:
|
|
* - Process returns non-zero exit status.
