strings. Here's one: no matter how much of the string you copy, the destination string must be space-padded for the entire remaining area. Specifically, even if you call MPI_INFO_GET and tell MPI to only copy a max of N characters of the value into the result string, if the Fortran string is M characters (where M > N), MPI must space-pad the remaining (M-N) characters to be spaces. So you're supposed to obey the argument to MPI_INFO_GET... sorta. Precedents: * http://www.ibiblio.org/pub/languages/fortran/ch2-13.html * LAM/MPI * Sun CT MPI This commit was SVN r11412.
