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.
