class MachOPlatform::MachOPlatformPlugin

Declaration

class MachOPlatform::MachOPlatformPlugin : public Plugin { /* full declaration omitted */ };

Description

Plugin instances can be added to the ObjectLinkingLayer to receive callbacks when code is loaded or emitted, and when JITLink is being configured.
