Subject: Retire env.h
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/doc/datamaps.china.min.js?a=commitdiff_plain;h=5f6c420586374d552d4a81aa129ada5aa46b797d;p=minix.git

Retire env.h

This was a MINIX3-specific header file placed outside of the minix/
header subdirectory, with its definitions duplicated in the more
standard minix/sysutil.h header.

Also make env_prefix(3) take constant pointers.

Change-Id: I243c38eb38e24eb98f0c0dddf7f340e7fec255f4
