It's my first time posting to users mailing list so hello everyone.
I'm currently optimizing code of my server written in Swift. To do that
reliably I want to be able to measure how long it takes to execute specific
methods.
On OSX I'm using mach_absolute_time() that I've wrapped in a struct for easier
interaction and it works fine. Now I'd like to do the same tests on a copy of
my actual platform that runs Ubuntu 15.10.
Mach0 library that I use is not available on Linux, instead I could use
gettimeofday or clock_gettime. For that I would have to expose time.h to my
swift code, however I'm unsure how to do it exactly.
I have started putting my timing struct in a swift package as a first step. Now
I'm stuck and here are my questions:
* How exactly do I use clang's modulemap with package manager?
* How do I make modulemap include time.h only on Linux?
* Is it necessary to include full path to time.h header or I can omit it in
case of system headers?
Here is a link to my package for future reference (no linux code there for now).

Also, if anyone is aware of a package that uses C library in place of OSX C
method to work cross-platform please let me know. It would be a great guidance
for me as I have a very vague idea of how package manager and C libs import
work.

M. Kalinowski
