MPI error handler (handle).

.SH DESCRIPTION
|
|
.ft R
|
|
Note that use of this routine is \fIdeprecated\fP as of MPI-2. Please use MPI_Comm_create_errhandler instead.
|
|
.sp
|
|
This deprecated routine is not available in C++.
|
|
.sp
|
|
Registers the user routine function for use as an MPI exception handler. Returns in errhandler a handle to the registered exception handler.
|
|
.sp
|
|
In the C language, the user routine should be a C function of type MPI_Handler_function, which is defined as
|
|
.sp
|
|
.nf
|
|
typedef void (MPI_Handler_function)(MPI_Comm *, int *, \&...);
|
|
.fi
|
|
.sp
|
|
The first argument is the communicator in use. The second is the error code
|
|
to be returned by the MPI routine that raised the error. If the routine would have returned MPI_ERR_IN_STATUS, it is the error code returned in the status for the request that caused the error handler to be invoked. The remaining arguments are stdargs arguments whose number and meaning is implementation-dependent. An implementation should clearly document these arguments. Addresses are used so that the handler may be written in Fortran.
|
|
|
|
.SH NOTE
|
|
.ft R
|
|
The MPI-1 Standard states that an implementation may make the output value (errhandler) simply the address of the function. However, the action of MPI_Errhandler_ free makes this impossible, since it is required to set the value of the argument to MPI_ERRHANDLER_NULL. In addition, the actual error handler must remain until all communicators that use it are freed.
|
|
|
|
.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. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
