Compiler Warning (level 1) C4006

  • Artikkeli

#undef expected an identifier

The #undef directive did not specify an identifier to undefine. The directive is ignored. To resolve the warning, be sure to specify an identifier. The following sample generates C4006:

// C4006.cpp
// compile with: /W1
#undef   // C4006

// try..
// #undef TEST

int main() {
}
