Subject: process-util: replace PTR_TO_PID() and PID_TO_PTR macro by inline functions
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=b5d8dc4252a54e865fa5f63d24556632e491953e;p=elogind.git

process-util: replace PTR_TO_PID() and PID_TO_PTR macro by inline functions

This way we gain some typesafety at no cost.
