@CHIP-RTOS C Library - RTOS API
Unconditionally free a resource semaphore. The
resource's usage count is set to zero and the resource is freed.
int RTX_Free_Sem ( int semID );
- The semaphore ID of a resource semaphore
acquired by a call to RTX_Create_Sem.
- 0 on success else
- The resource will immediately be given to the task (if any) which is
waiting at the head of this semaphore's wait queue. Task rescheduling
occurs immediately if necessary.
This function is similar to
RTX_Release_Sem function unwinds the usage count from nested calls to
RTX_Reserve_Sem one count per call.
This RTX_Free_Sem function clears the count, immediately erasing the affect
of several nested calls to RTX_Reserve_Sem.
- This library function invokes a RTOS software interrupt.
