NAME

       MPI_Info_free - Frees an info object.

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Info_free(MPI_Info *info)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_INFO_FREE(INFO, IERROR)
            INTEGER        INFO, IERROR

C++ Syntax

       #include <mpi.h>
       void MPI::Info::Free()

INPUT/OUTPUT PARAMETER

       info      Info object (handle).

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_Info_free frees info and sets it to MPI_INFO_NULL.

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.
