Subtract from the current value, returning the previous value. `T` must be an integer or pointer type. If `T` is a pointer type, the provenance of `src` is ignored: both the return value and the new value stored at `*dst` will have the provenance of the old value stored there.

Bitwise xor with the current value, returning the previous value. `T` must be an integer or pointer type. If `T` is a pointer type, the provenance of `src` is ignored: both the return value and the new value stored at `*dst` will have the provenance of the old value stored there.

Stores a value if the current value is the same as the `old` value. `T` must be an integer or pointer type.

This page lists tutorials for SVG.

SVG makes use of a number of data types. This article lists these types along with their syntax and descriptions of what they're used for.

There are several basic shapes used for most SVG drawing. The purpose of these shapes is fairly obvious from their names. Some of the parameters that determine their position and size are given, but an element reference would probably contain more accurate and complete descriptions along with other properties that won't be covered in here. However, since they're used in most SVG documents, it's necessary to give them some sort of introduction.
