[Mono-dev] [RFC 5/8] io-layer: Define makedev for Haiku

[Andreas Färber]

Hey guys,

First, Haiku has the POSIX dev_t type declared in sys/types.h:
http://www.opengroup.org/onlinepubs/9699919799/basedefs/sys_types.h.html

Linux, BSDs, Solaris, OSX all seem to have a makedev macro or function  
to construct the final dev_t value from major and minor values (and  
major and minor macros/functions to obtain the individual values  
again). The stub implementation below is from FreeBSD iirc, OSX uses a  
different shift.

Should some implementation be added to Haiku?

Second, the use of makedev here comes from trying to parse a dev_t  
value from a string in a /proc/*/map[s] file [1], in load_modules [2].  
Apparently Haiku does not have /proc at all.
On Mac OS X, Mono uses _dyld_get_image_* functions instead [3].

What could I use on Haiku to enumerate process modules, from C code?

Thanks,
Andreas
