MPI_Errhandler_create
Creates an MPI-style errorhandler 
Synopsis
#include "mpi.h"
int MPI_Errhandler_create( function, errhandler )
MPI_Handler_function *function;
MPI_Errhandler       *errhandler;
Input Parameter
- function  
-  user defined error handling procedure 
Output Parameter
- 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 
ofMPI_Errhandler_free makes this impossible, since it is required to set 
thevalue of the argument to MPI_ERRHANDLER_NULL.  In addition, the 
actualerror handler must remain until all communicators that use it 
arefreed.
Notes for Fortran
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) 
havean additional argument ierr at the end of the argument list.  
ierris an integer and has the same meaning as the return value of the 
routinein C.  In Fortran, MPI routines are subroutines, and are invoked with 
thecall statement.
All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type 
INTEGERin Fortran.
Errors
All MPI routines (except MPI_Wtime and MPI_Wtick) return an error value;
C routines as the value of the function and Fortran routines in the 
lastargument.  Before the value is returned, the current MPI error handler 
iscalled.  By default, this error handler aborts the MPI job.  The error 
handlermay be changed with MPI_Errhandler_set; the predefined error 
handlerMPI_ERRORS_RETURN may be used to cause error values to be returned.
Note that MPI does not guarentee that an MPI program can continue 
pastan error.
- MPI_SUCCESS  
-  No error; MPI routine completed successfully.
- MPI_ERR_INTERN  
-  This error is returned when some part of the MPICH 
implementation is unable to acquire memory.
