[PECL-DEV] What is "module_number"?

I got it working. Turns out "#if HAVE_RAWSOCKETS" will evaluate to true 
in php_rawsockets.h but to false in rawsockets.c. Not sure why this is, 
but when I took "#if HAVE_RAWSOCKETS" out of rawsockets.c (and left it 
in php_rawsockets.h), it started working. I get the right output from nm 
now, PHP loads the extension, it prints phpinfo() information as 
requested ... all in all, it works well.

Now, I have another question. There's a little-documented integer called 
module_number that is implicitly declared inside the PHP_MINIT_FUNCTION. 
However, module_number does not seem to be available inside a 
PHP_FUNCTION, and I need it to be. Does anyone know what exactly this 
variable is and does and how I can have it made available inside a 
PHP_FUNCTION?

Thanks,

Nick
