Note: You cannot call LMX_GetErrorMessage from the heartbeat callback functions (see Heartbeats and LMX_SetOption). Instead, you may call LMX_GetErrorMessageSimple.
The following is a basic example of using LMX_GetErrorMessage, which returns a detailed error message for the last LM-X function call that occurred.
