Detailed Description

This group contains the API Mutex Handler implementation.

This handler provides routines to ensure mutual exclusion in a thread context at the API level.

Function Documentation

bool _API_Mutex_Is_owner ( const API_Mutex_Control * mutex )

Checks if the specified API mutex is owned by the executing thread.

Parameters

[in] mutex The API mutex to check the owner from.

void _API_Mutex_Lock ( API_Mutex_Control * mutex )

Acquires the specified API mutex.

Parameters

[in,out] mutex The API mutex to acquire.

void _API_Mutex_Unlock ( API_Mutex_Control * mutex )

Releases the specified API mutex.

Parameters

[in,out] mutex The API mutex to release.
