.SH DESCRIPTION
|
|
.ft R
|
|
MPI_File_delete deletes the file identified by the file name
|
|
\fIfilename\fP, 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.

.SH 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.
|
|
.sp
|
|
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.
