The caller sleeps until the next transmit interrupt occurs for the designated queue. The sleep occurs on a counting semaphore so that the count accumulates for every transmit interrupt. When configured, transmit interrupts occur for every packet transmitted. A microsecond-resolution timeout value may be specified which is rounded to the nearest system clock tick, or INFINITE to indicate that the caller should block until the operation is complete.
Note: This call must be made if hpeOpen was called with the OUTPUT_INTERRUPT
flag set.
HPESTATUS hpeWaitForTransmitQueueComplete( HPEHANDLE devhandle, DWORD queue_index, DWORD timeout_us );

INFINITE
to indicate that the operation should not time out before completion. A status value indicating the success or failure of the operation:
E_OK |
The operation completed successfully. |
E_EXIST |
The handle given is not a handle for an open HPE interface. |
E_TIME |
The call timed out before the operation was complete. |
E_STATE |
The driver is not operating in transmit-interrupt mode. |
E_LIMIT |
The queue_index parameter is out of bounds for the current hardware. |
E_TRANSMISSION |
The physical link is down; no buffers can be added to the queue. If this condition is received, terminate any outstanding receive operation, then close the interface (hpeClose) and reinitialize the software before reopening the interface. |
