Robert Hensing	61381c9964	C API: Make nix_err_msg treat NIX_OK as having no message ... The documentation "solved" this by specifying a precondition, but let's just make it more robust, and not leak irrelevant messages that might linger. We don't clear the message when clearing the status, in order to keep clearing fast; see last_err field doc.	2024-06-14 16:36:23 +02:00

José Luis Lafuente	01bad63c72	C API: Safer function pointer casting ... See https://github.com/NixOS/nix/pull/8699#discussion_r1554312181 Casting a function pointer to `void*` is undefined behavior in the C spec, since there are platforms with different sizes for these two kinds of pointers. A safe alternative might be `void (*callback)()`	2024-04-12 21:41:15 +02:00
