Function pointer invocation.

// Ensure that the global libapi library g_api is correctly initialized.
flexda_custom_api_t g_api;
uint32_t g_test_log_module[7] = {};
int ret = flexda_log_register("TEST");
if (ret >= 0) {
    g_test_log_module[0] = ret;
}
// Directly call the log function in the global libapi library.
g_api.flexda_log(4, g_test_log_module[0], "This is an err log.\n");
g_api.flexda_log(FLEXDA_LOG_WARNING, g_test_log_module[0], "This is a warning(macro level) log.\n");
g_api.flexda_log(FLEXDA_LOG_ERR, g_test_log_module[0], "This is a err log with variable var = 0x%x.\n", var);
// Use the macro function provided by libapi.h.
flexda_log(ERR, g_test_log_module[0], "This is err log string.\n");
flexda_log(INFO, g_test_log_module[0], "This is a info log with variable var = 0x%x.\n", var);
