global anonymous unions
-
hi all, i have a question about using global anonymous unions in more than one .cpp file. if i have this code:
static union {int y; int z;};in one of my source files, how do i declare it in a header file so it can be used elsewhere. These approaches do not work:extern static union {int y; int z;}; extern union {int y; int z;}; extern int y; extern int z;If I take the 'static' off, i get the following message:test.cpp(9) : error C2646: global anonymous unions must be declared staticBut static means internal linkage, so does that mean this is impossible? Thanks in advance, John -

Thanks in advance, Johnwhy using an anonymous union ? just give it a name !!

int x;
int y;

the problem is i can only use one storage-class specifier, but static is required so i can't use extern. this current method works fine if i only need to access it through one source file, but my project has many source files and requires the members of this union to be accessed through many of those files. here is my current code, please post yours that works:
// main.h extern union {int y; int z;}; // test.cpp #include "main.h" void do_something() { y = z; } // main.cpp static union {int y; int z;}; void main() { do_something(); }i appreciate it, John -
