Function documentation


uint32_t VcmpPluginInit(PluginFuncs* funcs, PluginCallbacks* callbacks, PluginInfo* info)

The entry point for all server plugins. The server checks to see if a plugin exports this function; if present, the function is called so the plugin can set up callbacks, provide information about itself, and save the PluginFuncs pointer in order to call SDK functions later.

All plugins should populate

Returns:1 on success, 0 on error


Do not call attempt to create entities here and avoid performing any substantial logic here. You should instead use PluginCallbacks.OnServerInitialise() to perform initialization.

Failing to follow these guidelines may crash the server at startup.


When compiling for Windows, this function needs to be annotated with __declspec(dllexport), like so:

__declspec(dllexport) uint32_t VcmpPluginInit(...)

Likewise, when compiling using C++, the function needs to be annotated with extern "C", so a Windows plugin using C++ would look like this:

extern "C" __declspec(dllexport) uint32_t VcmpPluginInit(...)

When writing plugins in different languages for both Windows and Linux, it may be useful to use this macro to save time:

#ifdef WIN32
    #define PLUGINSPEC __declspec(dllexport)
    #define PLUGINSPEC

#ifdef __cplusplus
    #define PLUGINLINKAGE extern "C"


PLUGINEXPORT uint32_t VcmpPluginInit(...)

The PluginFuncs struct


The struct that encapsulates all plugin function calls. The server populates this struct with function pointers that call into the server core to perform actions.

A pointer to this struct is given in VcmpPluginInit(). Your plugin should hold onto this pointer in order to call API functions. Your plugin must not change any of the function pointers in this struct.

uint32_t PluginFuncs.structSize

The size of the PluginFuncs struct in bytes. Useful for checking if new functions added in a minor API version are present. If you’d like to retain backwards-compatibility with older servers, you can check the size of this struct before referencing newly added API functions.
