I want to create a shared object in zig that runs some code when it enters & exits a program via LD_PRELOAD, though I can't find much relating to this kind of thing.
The only way I can think of doing this is by just creating a 'wrapper' C program which has __attribute__((constructor)) and calls into my zig code, but it does seem a little clunky.

I don't think you can do it from zig code, but you can mix zig and c, so link .c file into your dynamic lib to get that

I mean you just need a globally unique symbol and
export const my_constructor_symbol: *const fn () callconv(.C) void linksection(".init_array") = &myConstructorFn;
fn myConstructorFn() callconv(.C) void {
}
Heh i was looking for something like that
coarse socket
@typeName(@TypeOf(opaque{})) to the rescue for unique names
hardy kestrel
`@typeName(@TypeOf(opaque{}))` to the rescue for unique names
I dont think thatd work for this since you need to actually use it as an identifier not a string
is there a @export builtin maybe?
