Thanks for the feedback. I have attached a new draft for this ticket and incorporated your changes. Please give me any additional comments by the start of business Monday.

My only quibble would be to change the last sentence in his text from: The contents of returned MPI_CHAR values are only defined from index 0 through the location of the first null-terminating character. To: The contents of returned MPI_CHAR ***arrays*** are only defined from index 0 through the location of the first null-terminating character. -Dave On Feb 14, 2014, at 7:27 AM, Jeff Squyres (jsquyres) <[email protected]<mailto:[email protected]>> wrote: Here's the new text: ----- The use of the datatype MPI_CHAR in the MPI tool information interface implies a null-terminated character array, i.e. a string in the C language. If a variable has type MPI_CHAR, the value of the count parameter returned by MPI_T_CVAR_HANDLE_ALLOC and MPI_T_PVAR_HANDLE_ALLOC will include the null-terminating character. The value returned in count must be large enough to contain any valid value for the given variable. Arrays of type MPI_CHAR are only valid to the first null character. ----- There's a missing "," after "i.e." -- it should be "i.e.," I'd make some other minor changes: The use of the datatype MPI_CHAR in the MPI tool information interface implies a null-terminated character array, i.e., a string in the C language.

Please take a look at the red text for ticket 405 in the attached document and send your comments.
