NAME
    SCI_Upload - Uploads messages from a back end to the front end

C Syntax
    #include <sci.h>
    int SCI_Upload(int filter_id, sci_group_t group, int num_bufs, void *bufs[], int sizes[])

INPUT PARAMETERS
    filter_id
        The id of the message filter (IN).
    group
        The group which the message belongs to (IN).
    num_bufs
        The number of buffers of current message segment (IN).
    bufs
        The array of buffer locations of current message segment (IN).
    sizes
        The array of buffer sizes of current message segment (IN).

DESCRIPTION
    This subroutine is used to upload message from a back end to the front end. The
    message can be sent directly to the front end if set filter_id to SCI_FILTER_NULL,
    or can be sent to the filter indicated by filter_id if a new message filter is loaded 
    by SCI_Filter_load.

    This is a non-blocking call. The caller cannot assume that message transfer has 
    completed upon the return of the function. Instead, the handler function defined in 
    sci_info_t should be used to ensure the message arrival in the destination sides.

    For more information, please refer to SCI's online documents.

EXAMPLE
        {
                char msg[256];
                int sizes[1];
                void *bufs[1];
                ...
                bufs[0] = msg;
                sizes[0] = strlen(msg) + 1;
                SCI_Upload(SCI_FILTER_NULL, SCI_GROUP_ALL, 1, bufs, sizes);
        }
