INPUT/OUTPUT PARAMETER
----------------------
* ``info``: Info object (handle).

INPUT PARAMETERS
----------------
* ``key``: Key (string).
* ``value``: Value (string).

OUTPUT PARAMETER
----------------
* ``ierror``: Fortran only: Error status (integer).

DESCRIPTION
-----------

:ref:`MPI_Info_set` adds the (key,value) pair to *info* and overrides the value
if a value for the same key was previously set. The *key* and *value*
parameters are null-terminated strings in C. In Fortran, leading and
trailing spaces in *key* and *value* are stripped. If either *key* or
*value* is larger than the allowed maximums, the error MPI_ERR_INFO_KEY
or MPI_ERR_INFO_VALUE is raised, respectively.
