(sorry, for me subversion is code at-first-sight)
in the plugin it seems that this code happens:
//======================================================
svn_client_ctx_t ctx;
memset(&ctx, 0, sizeof(ctx));
// get the config based on the configDir passed in
svn_config_get_config(&ctx.config, c_configDir, pool);
// tell the auth functions where the config is
svn_auth_set_parameter(ab, SVN_AUTH_PARAM_CONFIG_DIR,
c_configDir);
ctx.auth_baton = ab;
ctx.log_msg_func = onLogMsg;
ctx.log_msg_baton = this;
ctx.notify_func = onNotify;
ctx.notify_baton = this;
ctx.cancel_func = onCancel;
ctx.cancel_baton = this;
#if (SVN_VER_MAJOR >= 1) && (SVN_VER_MINOR >= 2)
ctx.notify_func2 = onNotify2;
ctx.notify_baton2 = this;
#endif
//======================================================
so missing from here, as I understand is svn_client_create_context
