Seems no, because you wish to modify a value.
In some function it looks shorter:
int func(int value);

func(~value);

But value stay unchanged.

how about:

#define NOT(a) ((a)=~(a))
...
NOT(value)
...


however, be careful about the legibility of your code, since the value of the parameter is modified.

Only the increment and decrement operators have syntax like that - the only choices I know of are macros, function calls, and the form you posted - value ~= value.
