DTL_WAIT parameters

wait_mask

is a pointer to the wait identifier mask. The mask consists of two consecutive longwords.

number_set

is a pointer to the number of wait identifiers that were set by this function call. The value is updated after each DTL_WAIT function call completes.

mask_result

is a pointer to the result mask. The mask consists of two consecutive longwords. The result mask is updated after each DTL_WAIT function call completes.

timeout

is the maximum time (in milliseconds) that the client application will wait for this function call to complete. If the call does not complete before the specified time expires, control will be returned to the client application and the final I/O completion status will be set to DTL_E_TIME.

A timeout value of DTL_FOREVER (defined in Dtl.h) specifies that this function should not return until at least one of the expected wait identifiers becomes set. If one of these wait identifiers never becomes set, the I/O operation will never complete unless a response is received from the network interface.
