Hi, I was just wondering, is it good to use return without arguments in a void function as following: void SetMapLayer() { if( !Map ) return; layer = LAYER_MAP; } It works well but it is considered a good programming technic? TIA, Max....

Return from void functions in C - The void functions are called void because they do not return anything. “A void function cannot return anything” this statement is not always true. From a void function, we cannot return any values, but we can return
voidfunc(void){return; } is perfectly legal in avoidfunction. The legality of areturnstatement with an expression depends on the version of the C language you're using. The 1990 C standard says: Areturnstatement with an expression shall not appear in a function whose return type isvoid. ...

如果函数声明指定了返回类型为 void ,那么函数实现中就不需要使用 return 语句。 void 表示该函数不返回任何值,因此在函数体中不需要明确返回值。 比如: void myVoidFunction() { // 这里是函数体,不需要使用 return 语句 } 如果函数声明指定了其他返回类型(比如 float32),那么函数体中应该使用 return 语句返回...
