  <a name="1273951"> </a><font size=2  face="Verdana, Arial, Helvetica, sans-serif"><font  face="Verdana, Arial, Helvetica, sans-serif"><b>mutex_init_priority</b></font> initializes a mutex. Mutexes initialized with this function have the usual mutex semantics, except that when a task calls <font size=2 face=Courier><strong>mutex_lock()</strong></font> it is inserted into the queue of waiting tasks so that the list remains sorted by the task's priority, highest priority first. In this way when a task is removed from the front of the queue by <font size=2 face=Courier><strong>mutex_release()</strong></font>, it is guaranteed to be the task with the highest priority of all those waiting for the mutex.</font>
