Have them just return the information needed for the caller to produce an error message, and have the callers use the new cfile_ routines for reporting errors. This requires that the "write failure alert box" routine take the *input* file name as an argument, so that, on a merge, if the problem is that a record from a given input file can't be written out to the type of output file we're generating, the input file name can be given, along with the record number in that file.
