17.2.328.4. DESCRIPTION
MPI_Session_set_errhandler attaches a new error handler to a session. The error handler must be either a predefined error handler or an error handler created by a call to MPI_Session_create_errhandler.
17.2.328.5. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
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_Session_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.
