look at the 2ndusage of buf:
snprintf(buf, sizeof(buf),
"This is an entry widget in this window that<br/>"
"uses markup <b>like this</> for styling and<br/>"
"formatting <em>like this</>, as well as<br/>"
"<a href=X><link>links in the text</></a>, so enter text<br/>"
"in here to edit it. By the way, links are<br/>"
"called <a href=anc-02>Anchors</a> so you will need<br/>"
"to refer to them this way.<br/>"
"<br/>"
"Also you can stick in items with (relsize + ascent): "
"<item relsize=16x16 vsize=ascent href=emoticon/evil-laugh></item>"
" (full) "
"<item relsize=16x16 vsize=full href=emoticon/guilty-smile></item>"
" (to the left)<br/>"
"Also (size + ascent): "
"<item size=16x16 vsize=ascent href=emoticon/haha></item>"
" (full) "
"<item size=16x16 vsize=full href=emoticon/happy-panting></item>"
" (before this)<br/>"
"And as well (absize + ascent): "
"<item absize=64x64 vsize=ascent href=emoticon/knowing-grin></item>"
" (full) "
"<item absize=64x64 vsize=full href=emoticon/not-impressed></item>"
" or even paths to image files on disk too like: "
"<item absize=96x128 vsize=full
href=file://%s/images/sky_01.jpg></item>"
" ... end."
, elm_app_data_dir_get()
);
ok, not buffer overflow, but anyway, buf should be longer for this
