[CF-Devel] code question

[crossfire-devel-admin at archives.real-time.com]

in socket/info.c are these 2 functions.

What is their usage? I don't understand them in the context
of the other functions of info.c.

void flush_output_element(object *pl, Output_Buf *outputs)
{
    char tbuf[MAX_BUF];

    if (outputs->buf==NULL) return;
    sprintf(tbuf,"%d times %s", outputs->count, outputs->buf);
    print_message(NDI_BLACK, pl, tbuf);
    free_string(outputs->buf);
    outputs->buf=NULL;
    outputs->first_update=0;
}

/* Following checks the various buffers in the player structure and
 * other things, and stores/prints/whatever's the data, as appropriate.
 */

void check_output_buffers(object *pl, char *buf)
{
    int i, oldest=0;

    if (pl->contr->outputs_count<2) {
	print_message(NDI_BLACK, pl, buf);
	return;
    }
    else {
	for (i=0; i<NUM_OUTPUT_BUFS; i++) {
	    if (pl->contr->outputs[i].buf && 
		!strcmp(buf, pl->contr->outputs[i].buf)) break;
	    else if (pl->contr->outputs[i].first_update <
		pl->contr->outputs[oldest].first_update)
			oldest=i;
	}
	if (i<NUM_OUTPUT_BUFS) {
	    pl->contr->outputs[i].count++;
	    if (pl->contr->outputs[i].count>=pl->contr->outputs_count) {
		flush_output_element(pl, &pl->contr->outputs[i]);
	    }
	}
	else {
	    flush_output_element(pl, &pl->contr->outputs[oldest]);

	    pl->contr->outputs[oldest].first_update = pticks;
	    pl->contr->outputs[oldest].count = 1;
	    if (pl->contr->outputs[oldest].buf!=NULL)
		free_string(pl->contr->outputs[oldest].buf);
	    pl->contr->outputs[oldest].buf = add_string(buf);
	}
    }
}
