For those with high speed connections, the very large single file summary is still on line. Bit clear changes the specified bit to zero. Bit set changes the specified bit to one. Bit change modifies a specified bit, clearing a one bit to zero and setting a zero bit to one. In some processors, the value of the bit before modification is tested.
Bit test examines the value of a specified bit.
Bit field insert inserts a value into a bit field. Bit field extract extracts a signed or unsigned value from a bit field. Bit field test evaluates a bit field and sets or clears flags. Bit field test and set evaluates a bit field and set or clear flags then sets the bit field. Bit field test and clear evaluates a bit field and set or clear flags then clears the bit field.
