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

       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_INFO_SET(INFO, KEY, VALUE, IERROR)
            INTEGER        INFO, IERROR
            CHARACTER*(*)  KEY, VALUE

Fortran 2008 Syntax

       USE mpi_f08
       MPI_Info_set(info, key, value, ierror)
            TYPE(MPI_Info), INTENT(IN) :: info
            CHARACTER(LEN=*), INTENT(IN) :: key, value
            INTEGER, OPTIONAL, INTENT(OUT) :: ierror

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++ functions 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.
