MPI_File_close - Closes a file (collective).

#include <mpi.h>
int MPI_File_close(MPI_File *fh)

USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_FILE_CLOSE(FH, IERROR)
	INTEGER	FH, IERROR

USE mpi_f08
MPI_File_close(fh, ierror)
	TYPE(MPI_File), INTENT(INOUT) :: fh
	INTEGER, OPTIONAL, INTENT(OUT) :: ierror

#include <mpi.h>
void MPI::File::Close()

File handle (handle).

Fortran only: Error status (integer).

MPI_File_close first synchronizes file state, then closes the file associated with fh. MPI_File_close is a collective routine. The user is responsible for ensuring that all outstanding requests associated with fh have completed before calling MPI_File_close.

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. For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
