Assign bitset member to char
- by RedX
I have some code here that uses bitsets to store many 1 bit values into a char.
Basically
struct BITS_8 {
char _1:1;
(...)
char _8:1;
}
Now i was trying to pass one of these bits as a parameter into a function
void func(char bit){
if(bit){
// do something
}else{
// do something else
}
// and the call was
struct BITS_8 bits;
// all bits were set to 0 before
bits._7 = 1;
bits._8 = 1;
func(bits._8);
The solution was to single the bit out when calling the function:
func(bits._8 & 0x128);
But i kept going into //do something because other bits were set. I was wondering if this is the correct behaviour or if my compiler is broken. The compiler is an embedded compiler that produces code for freescale ASICs.
