MPI_Info_free(3)                   Open MPI                   MPI_Info_free(3)

NAME
       MPI_Info_free - Frees an info object.

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

Fortran Syntax
       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_INFO_FREE(INFO, IERROR)
            INTEGER        INFO, IERROR

Fortran 2008 Syntax
       USE mpi_f08
       MPI_Info_free(info, ierror)
            TYPE(MPI_Info), INTENT(INOUT) :: info
            INTEGER, OPTIONAL, INTENT(OUT) :: 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++  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.
