IServiceGroup::RequestDelayedService method (portcls.h)
The RequestDelayedService method requests service after the specified delay.
Syntax
void RequestDelayedService(
[in] ULONGLONG ullDelay
);
Parameters
[in] ullDelay
Specifies the absolute or relative time at which the timer is to expire. If the value of ulDelay is negative, the expiration time is relative to the current system time. Otherwise, the expiration time is absolute. The expiration time is expressed in system time units (100-nanosecond intervals). Absolute expiration times track any changes in the system time; relative expiration times are not affected by system time changes.
Return value
None
Remarks
Before calling RequestDelayedService to request a timer delay, initialize the timer by calling IServiceGroup::SupportDelayedService.
