}

This struct is used to access VapourSynth’s API when a plugin is initially loaded.

Fields

getAPIVersion: unsafe extern "system" fn() -> c_int

See getAPIVersion() in the struct VSAPI. Returns VAPOURSYNTH_API_VERSION of the library

configPlugin: unsafe extern "system" fn(identifier: *const c_char, pluginNamespace: *const c_char, name: *const c_char, pluginVersion: c_int, apiVersion: c_int, flags: c_int, plugin: *mut VSPlugin) -> c_int

Used to provide information about a plugin when loaded. Must be called exactly once from the VapourSynthPluginInit2() entry point. It is recommended to use the [vs_make_version] macro when providing the pluginVersion. If you don’t know the specific apiVersion you actually require simply pass VAPOURSYNTH_API_VERSION to match the header version you’re compiling against. The flags consist of values from VSPluginConfigFlags ORed together but should for most plugins typically be 0.

Returns non-zero on success.

registerFunction: unsafe extern "system" fn(name: *const c_char, args: *const c_char, returnType: *const c_char, argsFunc: VSPublicFunction, functionData: *mut c_void, plugin: *mut VSPlugin) -> c_int

See registerFunction() in the struct VSAPI,

Returns non-zero on success.
