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.
