“Void”的版本间的差异

2016年12月26日 (一) 20:49的版本

The void keyword is used only in function declarations. It indicates that the function is expected to return no information to the function from which it was called.

译：void用于函数声明。它表明该函数将不返回任何信息。

示例

// actions are performed in the functions "setup" and "loop"
// but  no information is reported to the larger program

void setup()
{
  // ...
}

void loop()
{
  // ...
}
