[Jochen Eisinger]
|
|
<BR>
|
|
<EM>> I've patch sanei_debug.h... now it creates one additional function
|
|
</EM><BR>
|
|
<EM>> for each backend that #includes sanei_debug.h (if there is no
|
|
</EM><BR>
|
|
<EM>> support for vararg macros). The output is the same as if it was
|
|
</EM><BR>
|
|
<EM>> compiled with vararg macros.
|
|
</EM><BR>
|
|
<P>I suggest removing the vararg macro implementation if the new one
|
|
<BR>
|
|
works equally well. It would be very nice to have portable code in
|
|
<BR>
|
|
the debug functions.
|
|
<BR>
|
|
<P><EM>> * debug_msg is no more static (maybe it should be renamed
|
|
</EM><BR>
|
|
<EM>> sanei_debug_msg to avoid conflicts)
|
|
</EM><BR>
|
|
<P>Good idea.
|
|
<BR>
|
|
<P><EM>> * the new per backend function needs to #include stdlib, string & stdarg
|
|
</EM><BR>
|
|
<P>Is this really a problem?
|
|
<BR>
|
|
<P><EM>> * it allocates memory
|
|
</EM><BR>
|
|
<P>This can be avoided by changing the arguments to debug_msg() to
|
|
<BR>
|
|
inclued the backend name as well:
|
|
<BR>
|
|
<P> debug_msg (level, DBG_LEVEL, STRINGIFY(BACKEND_NAME), msg, ap);
|
|
<BR>
|
|
<P>Then the output can be printed with two vfprintf() calls unless stderr
|
|
<BR>
|
|
is a socket. If it is a socket, I guess there is no other way to make
|
|
<BR>
|
|
sure all the info is included in the syslog message but to allocate
|
|
<BR>
|
|
some memory. :-/
|
|
<BR>
|
|
<P>Why did you not make the DBG_LOCAL function static? I believe it
|
|
<BR>
|
|
should be.
|
|
<BR>
