Function core.bitop.bt

Tests the bit. (No longer an intrisic - the compiler recognizes the patterns in the body.)

int bt (
  const(ulong*) p,
  ulong bitnum
) pure nothrow @nogc;

Example

size_t[2] array;

array[0] = 2;
array[1] = 0x100;

assert(bt(array.ptr, 1));
writeln(array[0]); // 2
writeln(array[1]); // 0x100
