NAME¶
MPI_File_delete - Deletes a file.
SYNTAX¶
C Syntax
#include <mpi.h>
int MPI_File_delete(char *filename, MPI_Info info)
Fortran Syntax¶
INCLUDE 'mpif.h'
MPI_FILE_DELETE( FILENAME, INFO, IERROR)
CHARACTER*(*) FILENAME
INTEGER INFO, IERROR
C++ Syntax¶
#include <mpi.h>
static void MPI::File::Delete(const char* filename, const
MPI::Info& info)
- filename
- Name of file to delete (string).
- info
- Info object (handle).
OUTPUT PARAMETER¶
- IERROR
- Fortran only: Error status (integer).
DESCRIPTION¶
MPI_File_delete deletes the file identified by the file name
filename,
provided it is not currently open by any process. It is an error to delete the
file with MPI_File_delete if some process has it open, but MPI_File_delete
does not check this. If the file does not exist, MPI_File_delete returns an
error in the class MPI_ERR_NO_SUCH_FILE.
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.
