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. 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 ***must be large enough to include any valid value, including its null-terminating character.*** ***The contents of returned MPI_CHAR values are only defined from index 0 through the location of the first null-terminating character.*** On Feb 13, 2014, at 3:24 PM, Kathryn Mohror <[email protected]> wrote:
Hi all,
Please have a look at this since we have to decide if it's ready for a reading, and submit it to the forum for review on Monday if we do.

Hi all,
As we discussed in our call, I have drafted new text for ticket 405 which clarifies our intent for the MPI_CHAR datatype to represent strings in the tools interface. Please take a look at the red text for ticket 405 in the attached document and send your comments.
