}

@brief The structure that defines a plug-in to a host.

This structure is the first element in any plug-in structure using the OFX plug-in architecture. By examining its members a host can determine the API that the plug-in implements, the version of that API, its name and version.

For details see \ref Architecture.

Fields

pluginApi: *const i8

Defines the type of the plug-in, this will tell the host what the plug-in does. e.g.: an image effects plug-in would be a “OfxImageEffectPlugin”

apiVersion: i32

Defines the version of the pluginApi that this plug-in implements

pluginIdentifier: *const i8

String that uniquely labels the plug-in among all plug-ins that implement an API. It need not necessarily be human sensible, however the preference is to use reverse internet domain name of the developer, followed by a ‘.’ then by a name that represents the plug-in.. It must be a legal ASCII string and have no whitespace in the name and no non printing chars. For example “uk.co.somesoftwarehouse.myPlugin”

pluginVersionMajor: u32

Major version of this plug-in, this gets incremented when backwards compatibility is broken.

pluginVersionMinor: u32

Major version of this plug-in, this gets incremented when software is changed, but does not break backwards compatibility.

setHost: Option<unsafe extern "C" fn(*mut OfxHost)>

@brief Function the host uses to connect the plug-in to the host’s api fetcher

\arg \e fetchApi - pointer to host’s API fetcher

Mandatory function.

The very first function called in a plug-in. The plug-in \em must \em not call any OFX functions within this, it must only set its local copy of the host pointer.

\pre

• nothing else has been called

\post

• the pointer suite is valid until the plug-in is unloaded

mainEntry: Option<unsafe extern "C" fn(*const i8, *const c_void, *mut OfxPropertySetStruct, *mut OfxPropertySetStruct) -> i32>

@brief Main entry point for plug-ins

Mandatory function.

The exact set of actions is determined by the plug-in API that is being implemented, however all plug-ins can perform several actions. For the list of actions consult \ref ActionsAll.

Preconditions

• setHost has been called
