CmEmbedded_4c_transp CmGetLastErrorCode

Description

CmGetLastErrorCode returns the last set error code. Every API function/method call sends a request from the calling driver (on Windows: WibuCm32.dll) directly to CodeMeter License Server (on Windows: CodeMeter.exe). With the answer CodeMeter License Server always sends the last occurred error code back to the calling driver.

At this location the error code is stored in a global variable declared as Thread Local Storage (TLS). CmGetLastErrorCode returns this variable. If a problem in the calling driver occurs, an error code is also set at this global variable. Because of using Thread Local Storage the calling driver is thread safe.
