<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Well, this won't quite work, as appdata can be NULL. strlen isn't NULL safe.
As such, you'll need to do something like:
int escaped_len = (!ast_strlen_zero(appdata) ? 2 * strlen(appdata) : 0) + 1;
</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Thanks for the pointer ! No need to count the string length twice, just a null pointer check should suffice. Also need to set the escaped_len to 1 if appdata==NULL, so that it will be able to contain '\0'.</pre>
