MPI_Comm_attach_buffer(3) MPI MPI_Comm_attach_buffer(3)
NAME
MPI_Comm_attach_buffer - Attaches a user-provided buffer for buffered
send in the communicator
SYNOPSIS
int MPI_Comm_attach_buffer(MPI_Comm comm, void *buffer, int size)
int MPI_Comm_attach_buffer_c(MPI_Comm comm, void *buffer, MPI_Count size)
INPUT PARAMETERS
comm - communicator (handle)
buffer - initial buffer address (choice)
size - buffer size, in bytes (non-negative integer)
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_Comm_set_errhandler (for
communicators), MPI_File_set_errhandler (for files), and
MPI_Win_set_errhandler (for RMA windows). The MPI-1 routine
MPI_Errhandler_set may be used but its use is deprecated. 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; however, MPI implementations will
attempt to continue whenever possible.
MPI_SUCCESS
- No error; MPI routine completed successfully.
MPI_ERR_ARG
- Invalid argument. Some argument is invalid and is not
identified by a specific error class (e.g., MPI_ERR_RANK ).
MPI_ERR_COMM
- Invalid communicator. A common error is to use a null
communicator in a call (not even allowed in MPI_Comm_rank ).
MPI_ERR_OTHER
- Other error; use MPI_Error_string to get more information
about this error code.
