使用define实现复杂的函数定义

// set function template

#define XX_GCONF_SET_FUNC(TYPE, VALUE_TYPE) \
    gboolean xx_gconf_set_##TYPE(char *path, VALUE_TYPE value) \
    { \
        GConfClient* client = gconf_client_get_default(); \
        GError *error = NULL; \
    \
        gboolean result = gconf_client_set_##TYPE(client, path, value, &error); \
    \
        if(error != NULL) \
        { \
            XX_TRACE(XX_TRACE_LEVEL_ERROR, "Error occured while set gconf: %s\n", error->message); \
            g_error_free(error); \
            \
            result = PM_FAILED; \
        } \
    \
        return result; \
    }


//定义函数xx_gconf_set_bool
XX_GCONF_SET_FUNC(bool , gboolean);
