What is use of typedef in C? The typedef is a keyword used in C programmingto provide some meaningful names to the already existing variable in the C program. It behaves similarly as we define the alias for the commands. In short, we can say that this keyword is used to redefine the ...

value of a afrer swap(call by value) 20 value of b afrer swap(call by value) 10 the above function should have swapped already, as it shows result printed with in function But is it swapped? Let's check by Printing here... value of a after swap(call by value) 10 value of b ...
We could include types.h but instead let's just switch from ulong to directly using unsigned long. This removes the need for typedef'ing it in some of the tests, so also remove those. Signed-off-by: Andrew Davis <afd@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>...

'true' undeclared (first use in this function) or `false' undeclared (first use in this function) 就是说 bool, true, false 都是undeclared,原因很简单,因为真正的C中没有这些关键字,c和早期的c++里没有关键字bool,使用BOOL可以,但BOOL不是内置类型了,都是通过typedef或者宏来定义的,通常都会被定义成...
Finally, the last parameter is a pointer to your custom CallBack function. Just make sure that your function respects the same structure as the HAL excepts. You can find the correct structure in the p[Peripheral]_CallbackTypeDef (like pUART_CallbackTypeDef). See the examples below: ...
