I've started to work on 3.1 items. The first one is to allow the look up of variables by name instead of having to iterate through all variables until you find the one you want (assuming you know the name in advance). What do people think of this for supporting that functionality:
MPI_T_CVAR_GET_INFO_NAMED
IN name
OUT cvar_index
OUT verbosity
OUT datatype
OUT enumtype
OUT desc
INOUT desc_len
OUT bind
OUT scope
MPI_T_CVAR_GET_INFO_NAMED behaves similarly to MPI_T_CVAR_GET_INFO except that the lookup is done by control variable name instead of its index. All restrictions and requirements for MPI_T_CVAR_GET_INFO are the same for MPI_GET_CVAR_INFO_NAMED except that the cvar_index is now returned from the function, and name is an input.
Then define MPI_T_PVAR_GET_INFO_NAMED in a similar fashion.
