Defines version of the v3 plugin argument structs.

Whenever one or more of these structs are modified, this constant must be updated. A changelog should be appended in this comment as well, to make it easier to see what information is available in the different versions.

Version Comment 1 Initial plugin v3 structures providing the same API as the v2 plugin interface, X509 certificate information + a logging API for plug-ins.

2 Added ssl_api member in struct openvpn_plugin_args_open_in which identifies the SSL implementation OpenVPN is compiled against.

3 Added ovpn_version, ovpn_version_major, ovpn_version_minor and ovpn_version_patch to provide the runtime version of OpenVPN to plug-ins.

4 Exported secure_memzero() as plugin_secure_memzero()

5 Exported openvpn_base64_encode() as plugin_base64_encode() Exported openvpn_base64_decode() as plugin_base64_decode()

	)

This function is called by OpenVPN each time the OpenVPN reaches a point where plug-in calls should happen.

It only happens for those plug-in hooks enabled in openvpn_plugin_open_v3().

For the arguments, see the include/openvpn-plugin.h file for details on the function parameters

Parameters

handle	Pointer to the plug-in global context buffer, which need to be released by this function
type	Type of the hook
argv	String array pointer to arguments for the hook
envp	String array pointer to current environment variables

Returns: Must return OPENVPN_PLUGIN_FUNC_SUCCESS or OPENVPN_PLUGIN_FUNC_DEFERRED on success. Otherwise it should return OPENVPN_FUNC_ERROR, which will stop and reject the client session from progressing.

Parameters

v3structver	An integer containing the API version of the plug-in structs OpenVPN uses
