bit manipulation - C - Swap a bit between two numbers -

i tried code:

void swapbit(unsigned char* numba, unsigned char* numbb, short bitposition)//bitposition 0-x {     unsigned char oneshift = 1 << bitposition;      unsigned char bita = *numba & oneshift;     unsigned char bitb = *numbb & oneshift;      if (bita)         *numbb |= bita;     else         *numbb &= (~bita ^ oneshift);      if (bitb)         *numba |= bitb;     else         *numba &= (~bitb ^ oneshift); } 

to swap bit position x of , b because of if() think there's better.

also when see this:

*numbb &= (~bita ^ oneshift); 

i think there's easier way it. if have me, take :)

thanks in advance

first should set corresponding position in number 0, , or actual bit, removing of conditions:

*numbb &= ~oneshift; // set bit `0` *numbb |= bita;      // set actual bit value 

the same other number.
