MPI_File_set_errhandler(3) | Open MPI | MPI_File_set_errhandler(3) |
NAME¶
MPI_File_set_errhandler - Sets the error handler for a file.
SYNTAX¶
C Syntax¶
#include <mpi.h> int MPI_File_set_errhandler(MPI_File file, MPI_Errhandler errhandler)
Fortran Syntax¶
USE MPI ! or the older form: INCLUDE 'mpif.h' MPI_FILE_SET_ERRHANDLER(FILE, ERRHANDLER, IERROR) INTEGER FILE, ERRHANDLER, IERROR
Fortran 2008 Syntax¶
USE mpi_f08 MPI_File_set_errhandler(file, errhandler, ierror) TYPE(MPI_File), INTENT(IN) :: file TYPE(MPI_Errhandler), INTENT(IN) :: errhandler INTEGER, OPTIONAL, INTENT(OUT) :: ierror
C++ Syntax¶
#include <mpi.h> void MPI::File::Set_errhandler(const MPI::Errhandler& errhandler)
INPUT/OUTPUT PARAMETER¶
- file
- File (handle).
INPUT PARAMETER¶
- errhandler
- New error handler for file (handle).
OUTPUT PARAMETER¶
- IERROR
- Fortran only: Error status (integer).
DESCRIPTION¶
Attaches a new error handler to a file. The error handler must be either a predefined error handler or an error handler created by a call to MPI_File_create_errhandler.
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. 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.
