* mutex1e.c

* As for mutex1.c but with type set to PTHREAD_MUTEX_ERRORCHECK.

|

|
* Create a simple mutex object, lock it, unlock it, then destroy it.
|
||
|
|
* This is the simplest test of the pthread mutex family that we can do.
|
||
|
|
*
|
||
|
|
* Depends on API functions:
|

|
|
* pthread_mutexattr_settype()
|
||
|
|
* pthread_mutex_init()
|
||
|
|
* pthread_mutex_destroy()
