Thank you Mr. Icaza.
Is there more information on what uses the MapAttribute than what's in
Syscall.cs? Even though it's internal and I won't use it, I'd like to
understand how you solve the problem of ABI compatibility.
I'd like to set up a solution where copying the files from one
architecture to another simply works (assuming all dependencies from the
runtime are present), and the runtime/mylib chooses the most appropriate
native library (based on OSVersion and Syscall.uname) for all supported
platforms. Something like:
* MyLib.dll (assembly)
* MyNativeLib.Linux.x86.so
* MyNativeLib.Linux.x64.so
* MyNativeLib.FreeBSD.x86.so
* MyNativeLib.Darwin.x86.so
* MyNativeLib.Win.x86.dll (windows native)
* MyNativeLib.Win.x64.dll (windows native)
* MyNativeLib.[dll|so] (backup for local builds)
Your solution (Mono.Unix.Native) looks different, more compact, but I'm
not sure if/how it supports side-by-side. My solution requires a lot of
work, duplicate code with small changes in defining the
structs/DllImports with different offsets and library names.
I've yet to look into the Dll mapping mechanism of Mono if that's also
suitable.
Thank you very much and for giving me the opportunity to use Mono.
Regards,
Jason.

For something like libc, you can use an approach similar to what
Mono.Posix does, where an intermediate C glue file acts as a bridge
between the API differences.
See the P/Invokes for the Mono.Posix assembly, and its supporting glue
code in mono/support/

Hello,
I'm investigating the best way on how to support multiplatform
software especially when using P/Invokes, but have not found any
reasonable advice on the Wiki.
Can someone point to me on how to handle different architectures,
especially when the underlying libc might use different structures
or API signatures?
Thanks,
Jason.
