MPI_File_delete

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)
 
 

 

INPUT PARAMETERS

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.
