没有 API 函数可以做到这一点。您可以将此函数用于AppMessageResult
枚举:
char *translate_error(AppMessageResult result) {
switch (result) {
case APP_MSG_OK: return "APP_MSG_OK";
case APP_MSG_SEND_TIMEOUT: return "APP_MSG_SEND_TIMEOUT";
case APP_MSG_SEND_REJECTED: return "APP_MSG_SEND_REJECTED";
case APP_MSG_NOT_CONNECTED: return "APP_MSG_NOT_CONNECTED";
case APP_MSG_APP_NOT_RUNNING: return "APP_MSG_APP_NOT_RUNNING";
case APP_MSG_INVALID_ARGS: return "APP_MSG_INVALID_ARGS";
case APP_MSG_BUSY: return "APP_MSG_BUSY";
case APP_MSG_BUFFER_OVERFLOW: return "APP_MSG_BUFFER_OVERFLOW";
case APP_MSG_ALREADY_RELEASED: return "APP_MSG_ALREADY_RELEASED";
case APP_MSG_CALLBACK_ALREADY_REGISTERED: return "APP_MSG_CALLBACK_ALREADY_REGISTERED";
case APP_MSG_CALLBACK_NOT_REGISTERED: return "APP_MSG_CALLBACK_NOT_REGISTERED";
case APP_MSG_OUT_OF_MEMORY: return "APP_MSG_OUT_OF_MEMORY";
case APP_MSG_CLOSED: return "APP_MSG_CLOSED";
case APP_MSG_INTERNAL_ERROR: return "APP_MSG_INTERNAL_ERROR";
default: return "UNKNOWN ERROR";
}
}
我使用该pebble analyze-size
命令来测量内存影响。此功能将花费您额外的 228 字节程序存储器。对于大多数开发人员来说,这可能是值得的;)
这就是您使用上述函数的方式,例如在丢弃的消息处理程序中:
static void appmsg_in_dropped(AppMessageResult reason, void *context) {
APP_LOG(APP_LOG_LEVEL_DEBUG, "In dropped: %i - %s", reason, translate_error(reason));
}
