TSPluginInit
************
Traffic Server plugin loading and registration.
Synopsis
========
.. code-block:: cpp
#include <ts/ts.h>
.. function:: void TSPluginInit(int argc, const char* argv[])
.. function:: TSReturnCode TSPluginRegister(TSPluginRegistrationInfo* plugin_info)
Description
===========
:func:`TSPluginInit` must be defined by all plugins. Traffic Server
calls this initialization routine when it loads the plugin and sets
:arg:`argc` and :arg:`argv` appropriately based on the values in
:file:`plugin.config`.
:arg:`argc` is a count of the number of arguments in the argument vector,
:arg:`argv`. The count is at least one because the first argument in the
argument vector is the plugins name, which must exist in order for
the plugin to be loaded.
:func:`TSPluginRegister` registers the appropriate SDK version specific in
:arg:`sdk_version` for your plugin. Use this function to make sure that the
version of Traffic Server on which your plugin is running supports the plugin.
Return Values
=============
:func:`TSPluginRegister` returns :const:`TS_ERROR` if the plugin registration
failed.
Examples
========
::
#include <ts/ts.h>
#define PLUGIN_NAME "hello_world"
void
TSPluginInit (int argc, const char * argv[])
{
TSPluginRegistrationInfo info;
info.plugin_name = PLUGIN_NAME;
info.vendor_name = "MyCompany";
info.support_email = "ts-api-support@MyCompany.com";
if (TSPluginRegister(&info) != TS_SUCCESS) {
TSError("[%s] Plugin registration failed", PLUGIN_NAME);
}
}
