| |
| .SH INPUT PARAMETERS |
| .ft R |
| .TP 1i |
| filter_id |
| The id of the message filter (IN). |
| .TP 1i |
| group |
| The group which the message belongs to (IN). |
| .TP 1i |
| num_bufs |
| The number of buffers of current message segment (IN). |
| .TP 1i |
| bufs |
| The array of buffer locations of current message segment (IN). |
| .TP 1i |
| sizes |
| The array of buffer sizes of current message segment (IN). |
| |
| .SH DESCRIPTION |
| .ft R |
| 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 \fIfilter_id\fP to \fBSCI_FILTER_NULL\fP, |
| or can be sent to the filter indicated by \fIfilter_id\fP if a new message filter is loaded |
| by \fBSCI_Filter_load\fP. |
| .sp |
| 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 \fIsci_info_t\fP |
| should be used to ensure the message arrival in the destination sides. |
| .sp |
| For more information, please refer to SCI's online documents. |
