Library SourceMod library name (server / engine / matchmaking)

Just a Signatures{} block, ready to drop into a gamedata file. Wire it up in your plugin however you like - SDKCall, DHooks, raw memory ops, or anything else.

Signatures + Functions block. The plugin uses DHookCreateFromConf - DHooks reads return type, this-type, calling convention, and argument types straight from the gamedata. Less boilerplate in the plugin, types travel with the gamedata.

DHooks plugin example

Type inference is best-effort from the C signature - sanity-check the DHooks types before shipping.
