Routine Description:
|
||
|
|
|
||
|
|
This function synchronizes the execution of the specified routine with
|
||
|
|
the execution of the service routine associated with the specified
|
||
|
|
interrupt object.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
Interrupt - Supplies a pointer to an interrupt object.
|
||
|
|
|
||
|
|
SynchronizeRoutine - Supplies a pointer to the function whose
|
||
|
|
execution is to be synchronized with the execution of the service
|
||
|
|
routine associated with the specified interrupt object.
|
||
|
|
|
||
|
|
SynchronizeContext - Supplies a context pointer which is to be
|
||
|
|
passed to the synchronization function as a parameter.
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
The value returned by the synchronization routine is returned as the
|
||
|
|
function value.
