Section: 3 (Bibliothèques de fonctions)
NAME
MPI_Errhandler_create - Creates an MPI-style errorhandlerSYNOPSIS
#include "mpi.h" int MPI_Errhandler_create( 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 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.NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement.All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in 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 last argument. Before the value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job. The error handler may be changed with MPI_Errhandler_set ; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarentee that an MPI program can continue past an 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.
