2.3.11. aocl_mmd_yield
The aocl_mmd_yield function is called when the host interface is idle. The host interface might be idle because it is waiting for the device to process certain events.
Syntax
int aocl_mmd_yield( int handle );Function Arguments
handle—A positive int value representing the handle to the board obtained from the aocl_mmd_open() call.Return Value
A nonzero return value indicates that the yield function performed work necessary for proper device functioning such as processing direct memory access (DMA) transactions.
A return value of 0 indicates that the yield function did not perform work necessary for proper device functioning.
Note: The yield function might be called continuously if it reports that it has necessary work to perform.
