#include <mpi.h>
int MPI_Errhandler_get(MPI_Comm \fIcomm\fP, MPI_Errhandler\fI *errhandler\fP)

.SH INPUT PARAMETER
.ft R
.TP 1i
comm
Communicator to get the error handler from (handle).

.SH OUTPUT PARAMETERS
.ft R
.TP 1i
errhandler
MPI error handler currently associated with communicator (handle).
.ft R
.TP 1i
IERROR
Fortran only: Error status (integer). 

.SH DESCRIPTION
.ft R
Note that use of this routine is \fIdeprecated\fP as of MPI-2. Please use MPI_Comm_get_errhandler instead. 
.sp
This deprecated routine is not available in C++. 
.sp
Returns in errhandler (a handle to) the error handler that is currently associated with communicator comm.
.sp
\fBExample:\fP A library function may register at its entry point the current error handler for a communicator, set its own private error handler for this communicator, and restore before exiting the previous error handler.  


.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.
