The set to modify.
The value to be set in
the. If this value already exists in
the, it is replaced. You may pass the value itself instead of a pointer to it if the value is pointer-size or less. If
theis fixed-size and setting the value would increase its size beyond its capacity, the behavior is undefined.
Depending on the implementation of the equal callback specified when creating
the, the value that is replaced by
value may not have the same pointer equality.
