A methodology is presented that will detect robustness failures in source code where I/O errors could occur and where there is no mechanism in place to handle the error. The details of the methodology are described showing how traditional compiler data flow analysis can be augmented to find structurally, within the application, code that can be used to perform error checking. In addition we describe how this code can be used to ensure the correctness of the I/O error checking.
