Utility library error string function?

Question

I've been working on an Error Handler library, culled mostly from these wonderful fora (Roberto!).  I can't seem to find an error code string generator for the functions in the Utiltiy Library though (in particular, functions like RenameFile, CopyFile, GetDir, SetDir, MakeDir, all the file i/o functions).
Most of those make mention to negative error types with some plain text explanations.  But there's no mention of a nice code-to-string converter function, as there is in other libraries.  For instance, for the RS232 library, there is GetRS232ErrorString.  For the Formatting & I/O library, there is GetFmtIOErrorString.
Am I not seeing it somewhere?  Inside the Utility library, there is a multithreading error code function called CmtGetErrorMessage.

You're right: the Urility Library does not incorporate a function that translates error codes to a meaningful text. I suppose this is due to the fact that error codes partly overlap, so a unique function could not be used.
Just as an example, error -1 means File not found in almost all file I/O library functions, but it translates to No files found matching the search criteria in GetFirstFile () , to No more files in GetNextFiles () and Invalid Parameters in MakePathname ().
Another example: error -2 means GetFirstFile must be called before if returned by GetNextFile (), and Resulting pathname too long if returned by MakePathname ().
And this considering only File I/O section of the library!
While developing my own toolbox of utilities, I have created the following function, which I know is far from perfect and covers only file I/O functions:
char * CVIFUNC GetULibFileIOErrMsg (int error)
// Messages associated to error codes returned by functions in File Utilities class in Utility Library
switch (error) {
case 0: return "Success";
case -1: return "One of the path component not found";
case -2: return "Resulting pathname longer than 260 chars";
case -3: return "General I/O error occurred";
case -4: return "Insufficient memory to complete operation";
case -5: return "Invalid path";
case -6: return "Access denied";
case -7: return "Specified path is a directory, not a file";
case -8: return "Disk is full";
case -9: return "New file already exists";
default: return "Unknown error";
return NULL;
Proud to use LW/CVI from 3.1 on.
