When the function niRFSA_ReadPowerSpectrumF64 times out, it returns an error code of 0xFFFA4E87 (-373113). niRFSA_error_message interprets the error code correctly ("The maximum time was exceeded before the operation completed"), but I was expecting a code of NIRFSA_ERROR_MAX_TIME_EXCEEDED (0xBFFA4002, -1074118654) instead, based on the values in niRFSAErrors.h, or possibly VI_ERROR_TMO (0xBFFF0015, -1073807339). I'm using version 15.0.0.49153 of niRFSA.dll.
Is there a list of the "real" error codes for the RFSA DLL available anywhere?
