NAME

       MPI_Info_set - Adds a key/value pair to info.

SYNTAX


C Syntax

       #include <mpi.h>
       int MPI_Info_set(MPI_Info info, char *key, char *value)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_INFO_SET(INFO, KEY, VALUE, IERROR)
            INTEGER        INFO, IERROR
            CHARACTER*(*)  KEY, VALUE

C++ Syntax

       #include <mpi.h>
       void MPI::Info::Set(const char* key, const char* value)

INPUT/OUTPUT PARAMETER

       info      Info object (handle).

INPUT PARAMETERS

       key       Key (string).

       value     Value (string).

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       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.

ERRORS

       Almost all MPI routines return an error value; C routines as the  value
       of  the  function  and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default  error  handler  is  set  to
       MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI  error  handler  is
       called.  By  default, this error handler aborts the MPI job, except for
       I/O  function  errors.  The  error  handler   may   be   changed   with
       MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN
       may be used to cause error values to be returned. Note  that  MPI  does
       not guarantee that an MPI program can continue past an error.
