326. Deprecated prototype definitions


Up: Defined Values and Handles Next: Info Keys Previous: Prototype definitions

The following are defined C typedefs for deprecated user-defined functions, also included in the file mpi.h.

/* prototypes for user-defined functions */ 
typedef int MPI_Copy_function(MPI_Comm oldcomm, int keyval, 
              void *extra_state, void *attribute_val_in, 
              void *attribute_val_out, int *flag); 
typedef int MPI_Delete_function(MPI_Comm comm, int keyval, 
              void *attribute_val, void *extra_state); 
typedef void MPI_Handler_function(MPI_Comm *, int *, ...); 
The following are deprecated Fortran user-defined callback subroutine prototypes. The deprecated copy and delete function arguments to MPI_KEYVAL_CREATE should be declared like these:


SUBROUTINE COPY_FUNCTION(OLDCOMM, KEYVAL, EXTRA_STATE, 
               ATTRIBUTE_VAL_IN, ATTRIBUTE_VAL_OUT, FLAG, IERR) 
   INTEGER OLDCOMM, KEYVAL, EXTRA_STATE, ATTRIBUTE_VAL_IN, 
         ATTRIBUTE_VAL_OUT, IERR 
   LOGICAL FLAG 

SUBROUTINE DELETE_FUNCTION(COMM, KEYVAL, ATTRIBUTE_VAL, EXTRA_STATE, IERR) 
    INTEGER COMM, KEYVAL, ATTRIBUTE_VAL, EXTRA_STATE, IERR 
The deprecated handler-function for error handlers should be declared like this:


SUBROUTINE HANDLER_FUNCTION(COMM, ERROR_CODE, .....) 
   INTEGER COMM, ERROR_CODE
