Description:This little patch changes ast_test_flag and its friends to a macro and moves it from channel.h to utils.h.

I wanted to use this to help trim down some of the other structs throughout asterisk.

How about doing the rest of the flag test/set things too?

Won't the compiler just treat the "static inline" functions as the equivalent of macros anyway, but with the distinct advantage of compile-time type checking?

Well, the presumed purpose of converting to  macro is exactly to eliminate the type checking so that it can be used with more than one structure (e.g. a sip_pvt, thus allowing us to condense the sip pvt structure by many many bytes).

Ahh, right, I missed that.

In other projects they declare a "flag holder" type (typedef for an int32 or something) and then the inline functions work off of that type. That means the calls would look something like:

ast_set_flag(chan->flags, AST_FLAG_WRITE_INT)

which is a little more verbose, but usable with as many structures as you want.

I uploaded a new patch that changes all of those flag functions to macros.

Fixed in CVS, thanks!
