| #define CCXX_BIT_CLEAR | ( | N, | |||
| BIT | ) | (((N) &= ~(1 << (BIT)))) |
Clear the bit at index BIT (where 0 corresponds to the LSB) in N.
The arguments are evaluated only once.
| #define CCXX_BIT_READ | ( | N, | |||
| BIT | ) | ((((N) & (1 << (BIT))) == 0) ? 0 : 1) |
Read the bit at index BIT (where 0 corresponds to the LSB) in N.
Returns 0 or 1. The arguments are evaluated only once.
| #define CCXX_BIT_SET | ( | N, | |||
| BIT | ) | ((N) |= (1 << (BIT))) |
Set the bit at index BIT (where 0 corresponds to the LSB) in N.
The arguments are evaluated only once.
| #define CCXX_BIT_TEST | ( | N, | |||
| BIT | ) | (((N) & (1 << (BIT))) != 0) |
Test the bit at index BIT (where 0 corresponds to the LSB) in N.
Returns true if the bit is set, false otherwise. The arguments are evaluated only once.
| #define CCXX_BIT_WRITE | ( | N, | |||
| BIT, | |||||
| VALUE | ) | ((VALUE) ? CCXX_BIT_SET((N), (BIT)) : CCXX_BIT_CLEAR((N), (BIT))) |
Write the bit at index BIT (where 0 corresponds to the LSB) in N.
VALUE is zero (or false) to clear the bit, nonzero (or true) to set the bit. The arguments are evaluated only once.
