Syntax

Copy
bool RtfwGetPIDByScheduledID(
    [in]    RTFW_SCHEDULED_ID scheduledID,
    [out]   unsigned int * ProcessID
);

Parameters

[in] scheduledID

Identifies a configured scheduled process by its scheduled launch order, which is returned to the client by RtfwCreateScheduledProcess in field ScheduledID of structure RTFW_SCHEDULED_PROCESS.

[out] ProcessID

Returns the last known or currently running PID of a scheduled process. Returns 0 if the Scheduled Process has never run.

Return Value

If the function succeeds, it returns TRUE. If the function fails, it returns FALSE. Call GetLastError to obtain an error code.

Possible error codes:

Error code Meaning

ERROR_INVALID_PARAMETER

One of the parameters of this function is NULL, or a field within the structure is invalid.

RT_ERROR_REGISTRY_MISSING

Could not find a PID value. This indicates the scheduled process has never been run.

RT_ERROR_SCHEDULED_PROCESS_NOT_FOUND

Could not find a scheduled process that matches the specified scheduledID.

Remarks

This function has locking to allow for thread safety. It shares a lock with all other scheduled process functions.

If the Subsystem is running when the RtfwGetLocalMemoryConfiguration API is called, the values returned by this function may differ from the values currently in use by the Subsystem.
