int sqlite3_bind_text(sqlite3_stmt*, int, const char*, int n, void(*)(void*));
It doesn't return a (void *) - it returns void. The (*) is part of the
function pointer declaration. The last function takes a pointer to memory
to free, e.g. semantically compatible with free().
For the full description of the semantics of the final argument, see:
http://www.sqlite.org/capi3ref.html#sqlite3_bind_blob
Ha! That's the full description that left me with my questions in the
first place!!
though it is admittedly somewhat confusing that one passes a (char const *)
as opposed to (char *) even when expecting (depending on the value of the
last parameter) it to be freed.
Here's an example of its usage:
http://www.adp-gmbh.ch/sqlite/bind_insert.html
Ha!! That example doesn't use the destructor arg.
But it's OK; I think I can finger this out.
