From: Ben Kaduk Date: Fri, 6 Dec 2013 20:24:58 +0000 (-0500) Subject: Add rxgk boilerplate X-Git-Tag: openafs-stable-1_8_0pre1~663 X-Git-Url: https://git.openafs.org/?p=openafs.git;a=commitdiff_plain;h=ee56e925f0c6484ac58e23ccdd1b1bf1a3760505;hp=e156fae7a1866d1b00a1d9252c0a775128e2f033 Add rxgk boilerplate Just the skeleton of what needs to be there. The actual import is split over multiple commits, to make the reviewer's burden more manageable. Error table, protocol description, and stubs for the security object routines, with header to declare them. The public header rxgk.h currently only contains a few typedefs and the NewSecurityObject prototypes, and includes the RPC interface and com_err code headers.
