Referring to this pointer in a static assert?
- by Tyson Jacobs
Is it possible to write a static assert referring to the 'this' pointer? I do not have c++11 available, and BOOST_STATIC_ASSERT doesn't work.
struct blah
{
void func() {BOOST_STATIC_ASSERT(sizeof(*this));}
};
Produces:
error C2355: 'this' : can only be referenced inside non-static member functions
error C2027: use of undefined type 'boost::STATIC_ASSERTION_FAILURE'
In MSVC 2008.
Motivation:
#define CLASS_USES_SMALL_POOL() \
void __small_pool_check() {BOOST_STATIC_ASSERT(sizeof(*this) < SMALL_MALLOC_SIZE;} \
void* operator new(size_t) {return SmallMalloc();} \
void operator delete(void* p) {SmallFree(p);}
