MPI_File_delete - Deletes a file.
C Syntax
#include <mpi.h>
int MPI_File_delete(char *filename, MPI_Info info)
INCLUDE ’mpif.h’
MPI_FILE_DELETE(FILENAME, INFO, IERROR)
CHARACTER*(*) FILENAME
INTEGER INFO, IERROR
#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).
- IERROR
- Fortran only: Error status (integer).
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.
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.
