X: TAnyType |
):LongInt; |
BitSizeOf returns the size, in bits, of any variable or type-identifier. For regular variables or types, this is the same as SizeOf multiplied by 8, but for bitpacked records, the result may be different.
| Remark: | This isn't really a RTL function. Its result is calculated at compile-time, and hard-coded in the executable. |
