@brief This file contains functions for resource management (mutex operations).
|
||
|
|
The functions implementations are generally just wrappers to different operating system calls.
|
||
|
|
None of the described functions will check the input parameters so the behavior
|
||
|
|
of the APIs in illegal parameters case is dependent on the operating system behavior.
