MPI_Errhandler_create - Creates an MPI-style errorhandler
Input Parameters:
. function - user defined error handling procedure
Output Parameters:
. errhandler - MPI error handler (handle)
Notes:
The MPI 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.
.N ThreadSafe
.N Deprecated
The replacement routine for this function is 'MPI_Comm_create_errhandler'.
.N Fortran
.N Errors
.N MPI_SUCCESS
.N MPI_ERR_EXHAUSTED
.seealso: MPI_Comm_create_errhandler, MPI_Errhandler_free
