Allows casting const-ness away from an expression, but doesn't allow changing the type. Enforcement of the latter currently only works for gcc-like compilers. Note that it is not safe to cast const-ness away if the result will ever be modified (it would be undefined behavior). Doing so can cause compiler mis-optimizations or runtime crashes (by modifying read-only memory). It is only safe to use when the result will not be modified, but API design or language restrictions prevent you from declaring that (e.g. because a function returns both const and non-const variables). Note that this only works in function scope, not for global variables (it would be nice, but not trivial, to improve that). UNCONSTIFY() requires static assert which is a feature in its own right. |
