I have a couple of ideas about making function traces nicer:
1. Use of PP_SEQ interface to "parse" function name and arguments
int X::foo(char* buf, size_t len) { BOOST_TRACE_MEM_FUN( (foo)(buf, len) ); // ... }
[snip] I have been using some helper macros for tracing which use the boost PP library. Basically it looks liket this: int X::foo(char* buf, size_t len) { some_log_object << STREAM_VARS_SEQ((buf)(len)); } This expands to "buf=" << buf << ",len=" << len What I like most is that you can specify expressions during tracing like this: STREAM_VARS_SEQ((buf[0])(2*len)) which of course gets you "buf[0]=" << buf[0] << ",2*len" << 2*len While usage is not really restricted to tracing, that where it gets used currently.
