I'm trying to write some symbols to a file with MPI.  When I do that, I get an errorcode of 288 and the file can't be opened. I used command line: mpiexec -n 10 myapp.exe. I was searching for the errorcode but didn't find anything at all.

Go one step further.  Your error code doesn't mean anything by itself.  But, you can feed that code to MPI_Error_string and get something more human readable.  I have this function in every MPI-IO code I write:
