The WLTrialExtendExpiration function allows extending the current trial period. To extend the trial period in an application, we recommend using Trial Extension keys (Generated by WinLicense). The WLTrialExtendExpiration function is suitable for those applications which cannot accept WinLicense trial extension keys by design.

Parameters
NumDays
This parameter specifies the number of days to extend the trial.
NumExec
This parameter specifies the number of executions to extend the trial.
pExpDate
This parameter specifies a pointer to a SYSTEMTIME structure with the new expiration date.
Runtime
This parameter specifies the new runtime expiration to extend in trial mode.
GlobalTime
This parameter specifies the number of minutes to extend the usage of the protected application in trial mode.
Return Values
If the function succeeds, the return value is true.
If the function fails, the return value is false.
