.SH INPUT PARAMETER
.ft R
.TP 1.4i
errorclass
MPI error class (integer).

.SH OUTPUT PARAMETERS
.ft R
.TP 1.4i
errorcode
Error code returned by an MPI routine or an MPI error class (integer).
.ft R
.TP 1.4i
IERROR
Fortran only: Error status (integer). 

.SH DESCRIPTION
Creates a new error code associated with \fIerrorclass\fP and returns
its value in \fIerrorcode\fP.

.SH NOTES
.ft R
No function is provided to free error codes, as it is not expected
that an application will create them in significant numbers.
.sp
The value returned is always greater than or equal to MPI_ERR_LASTCODE.

.SH ERRORS
.ft R
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.
