VLScgSetClockTamperFlag

Syntax

int VLScgSetClockTamperFlag (VLScg_HANDLE iHandle, codeT *codeP, char *flag);

Argument	Description
iHandle	The instance handle for this library.

Description

Controls action on detection of clock tampering (being set back) on the machine.

Clock tamper check is only done when the License Manager starts up, but the License Manager does not exit on detection of tampering. Only those licenses that specify they want the check are denied, if tampering is detected. Other features will continue to be served by the License Manager. Even if someone sets the clock back after starting the License Manager, and then dynamically adding a tamper-sensitive license string, the License Manager detects it.

When the License Manager accepts a license string at start-up but detects later that the clock has been set back, it does not grant a license for the feature until the clock is reset to its correct value.

Returns

The status code VLScg_SUCCESS is returned if successful. Otherwise, it will return the following error codes:

Error Code	Description
VLScg_INVALID_INT_TYPE	If value is not a decimal number.
VLScg_INVALID_RANGE	If value is not in the range allowed.
