17.2.99. MPI_File_close

MPI_File_close - Closes a file (collective).

17.2.99.1. SYNTAX

17.2.99.1.1. C Syntax

#include <mpi.h>

int MPI_File_close(MPI_File *fh)

17.2.99.1.2. Fortran Syntax

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

17.2.99.1.3. Fortran 2008 Syntax

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

17.2.99.2. INPUT/OUTPUT PARAMETER

  • fh: File handle (handle).

17.2.99.3. OUTPUT PARAMETER

  • IERROR: Fortran only: Error status (integer).

17.2.99.4. DESCRIPTION

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.

17.2.99.5. ERRORS

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.

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.
