Declaration
Delphi
function GetConfigurationVariableString(Name: ShortString; var LenOfData: Integer): Pointer;
C/C++
SOPAD_API LPVOID SOPAD_GetConfigurationVariableString(char* Name, int* LenOfData);
ActiveX
HRESULT GetConfigurationVariableString([in] BSTR* Name, [out, retval] BSTR* Result);
Description
Get the Value for a specific Device system Variable
Arguments
Name: String;
e.g. "so.pad.security.open.event.cache" (note: returns the open state cache from Device)
LenOfData: Integer
Lenght of the result Value (Lenght of the Data content)
Return value
This function return a Pointer to the Data structure. This data can be casted to a struct vor interpretation.
e.g. result = "010000000E0001341C09060C03150001F39664000E0001341C09060C0315"
