.SH DESCRIPTION
|
|
.ft R
|
|
MPI_File_close first synchronizes file state, then closes the file
|
|
associated with
|
|
.I fh.
|
|
MPI_File_close is a collective routine. The user is responsible for
|
|
ensuring that all outstanding requests associated with
|
|
.I fh
|
|
have completed before calling MPI_File_close.
|
|
|
|
.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.
