Re: [ros-dev] [ros-diffs] [hbelusca] 62562: [EXT2] try_return() == try_return(S) with nothing in S . The code sometimes use it. Shut up MSVC warning C4003: not enough actual parameters for macro 'try_return'.

[Hermès BÉLUSCA - MAÏTO]

Hmmm also, is there any Cxxxx error code associated with that, on MSVC ?

That's illegal, macros can't be overloaded.

drivers/filesystems/ext2/inc/ext2fsd.h:64:0: warning: "try_return" redefined
[enabled by default]

You could try
#define try_return(...) { __VA_ARGS__; goto try_exit; }

If that doesn't do it, it might simply need a separate macro (I'm not sure
to what extent this is third party code though)

(also if these were the last instances of that -- and I think so --, we
might want to make 4003 an error)
