<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">You need to be sure to free datastore_id even if ast_strlen_zero(uid_channel_var) evaluates true. You've got a memory leak as it is right now.</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;">The easiest way to do this is just to move the ast_free() call to after the if (!ast_strlen_zero(uid_channel_var)) block. That way it gets freed no matter what.</pre>

Changes creation of character buffer to length of a pointer in characters + 3 (2 for 0x, 1 for terminating space)
That might not be adequate. Richard was saying something about pointers on other operating systems having other dividing symbols in them. Well, at least ':'s.
In my experiences though, a pointer is usually just something like 0x0123FEDC when printed with %p.</pre>
