I am converting C++ code to C code. Here is the code which needs to be converted-



struct new
enum new_enum:uint8_t
head = 1,
tail = 2,
data = 3,
;
;


How to convert this? Can someone explain what is uint8_t in enum? Is it assigning all variables to uint8_t?










share|improve this question






















  • converting C++ code to C code is quite unclear. Do you want to convert the the enum value to its underlying integral value ?

The code you provide cannot compile in C++, since the struct name is new.



Anyway, you can try to just drop the :uint8_t. This will change the strongly typed enum to a standard C one. If you are lucky everything will work. If in any other point you have an use of head, tail or data, it won't work. You can do this:



enum new_enum 
new_enum_head = 1,
new_enum_tail = 2,
new_enum_data = 3,
;


Ugly, but likely to work. Of course the enum will have to go out of the struct it was defined in. That again can cause a lot of grief, but less likely.
