Top of list Index page RTOS Semaphore Services Interrupt 0xAD service 0x15: RTX_DELETE_SEM, Delete a semaphore Parameters AH BX Removes specified semaphore from system. 0x15 (= RTX_DELETE_SEM) ID of the semaphore acquired by RTX_CREATE_SEM Return Value Comments DX =0 success AX: 0 DX!=0 failure AX: contains error code You must be certain that no other task, Interrupt Service Routine or Timer procedure is in any way using or about to use this semaphore. Failure to observe this restriction can lead to unpredictable faults. Related Topics Top of list Index page RTOS Semaphore Services Interrupt 0xAD service 0x16: RTX_FREE_RES, Free a resource semaphore Parameters AH BX The resource semaphore's use count is set to zero which unconditionally frees the resource. 0x16 (= RTX_FREE_RES) ID of the resource semaphore acquired from RTX_CREATE_SEM Return Value DX =0 success AX: 0 Page 192 / 400
Comments DX!=0 failure AX: contains error code Only the task owning the resource semaphore can make this call successfully. Error code -12 is returned if the calling task does not own the semaphore (or if the semaphore is a counting semaphore type which are not owned by tasks). This API is useful to unwind in one stroke N calls made to RTX_RESERVE_RES. Alternatively, the RTX_RELEASE_SEM API could be called N times to release the resource semaphore. After being freed, the resource will immediately be given to the task (if any) which is waiting at the head of this resource semaphore's wait queue. An immediate task switch occurs if this waiting task is higher priority than the calling task that just gave up ownership of this semaphore.

This function must not be called for resource type semaphores, as this will foul up the operation of the resource semaphore.
