Mmmm. Interesting idea... On Oct 3, 2014, at 3:55 AM, Marc-Andre Hermanns <[email protected]> wrote:

Hi all,

at the call we discussed that tools would have call the info function twice to make sure the name buffer is large enough to hold the full variable name.

Couldn't we define additional constants, such as MPI_T_PVAR_MAX_NAME_LEN, which indicate the maximum length a pvar name (in this example) can have. Then a tools can choose to pay in time (with two calls) or memory (with always allocating max memory) for a pvar name buffer.

This way we don't have to change the calls, and might mitigate the pain.

Cheers, Marc-Andre
