ffi_dlclose#

Release a library handle previously returned by dlopen.

Σύνοψη#

Peta::FFI::dlclose($lib);

Τι επιστρέφεται#

Always 1. The return value exists so the call composes cleanly in expressions; inspecting it tells you nothing about success.

Οριακές περιπτώσεις#

  • No argument - croaks with Peta::FFI::dlclose: requires library handle.

  • Zero or null handle - silently ignored. Passing 0 is safe and commonly used as an «already closed» sentinel.

  • Double close - passing a handle that has already been released is undefined behaviour at the dlclose level; keep a single owner per handle or null out your copy after closing.

  • Outstanding calls - closing a library while a pointer or string it returned is still in use is undefined behaviour. Copy everything you need out of the library first.
