custom read functions #39
Description
Hello!
It would be great if this library supported custom read functions as supported in libarchive:
Sometimes, none of the packaged "open" functions will work for you. In that case, you can use the lower-level `archive_read_open` function. This accepts three callbacks and a pointer to your data:
- An open callback. This is legacy and is never necessary and should not be used.
- A read callback.
- A close callback.
