Uninstalls current PSSDK version protocol driver.

Syntax:

function UninstallProtocol(pUniqueInstallId: PChar) : DWORD;

Parameters:

pUniqueInstallId

[in] Unique ID of the subject executing driver uninstallation.

Return values:

Description:

Since version 3.1 you can install PSSDK internal drivers statically using corresponding PSSDK functions, that allows your application to get full access to PSSDK functions under user account with restricted rights.

The driver uninstallation process goes the following way:

1. Driver loading status is set to "Manual" (manual driver loading, the same as it is implemented in the version 3.0 and earlier);

2. When the third and the second applications uninstall the driver, nothing happens: real uninstallation is executed by the last application.

To use this function administrator rights are required. This function doesn't require PSSDK to be initialized.

Example:

DWORD Res = HNPSManager.UninstallProtocol(PChar("MyCompanyNameMyAppNameWhateverElse"));
if (Res == HNERR_OK) MessageBox(...);
