Compiler Warning (level 2) C4094

  • Article

untagged 'token' declared no symbols

The compiler detected an empty declaration using an untagged structure, union, or class. The declaration is ignored.

Example

// C4094.cpp
// compile with: /W2
struct
{
};   // C4094

int main()
{
}

This condition generates an error under ANSI compatibility (/Za).
