Hi
Is it possible to display variable length data using g_snprintf? For the 802.11k AP channel report, the channel list is dependent on the tag_len which is variable.
tag_data_ptr = tvb_get_ptr (tvb, offset, tag_len);

strcpy(print_buff, "");
for (i = 0, n = 0; i < tag_len; i++) {
char    print_buff_idx[10];
ret = g_snprintf (print_buff_idx , SHORT_STR ,

"%02X ", tag_data_ptr[i]);
strcat(print_buff, print_buff_idx);
}

proto_tree_add_string (tree, hf_tag_channel_list, tvb, offset, tag_len, print_buff);
 

right now it is displaying as channel list: <and the last value it is 
holding>.
i want it to display all the supported channel list as channel list : 
1 6  etc. depending  on the tag_len.
Please suggest.

Thanks,

Soumya
