# HG changeset patch # User Ian Campbell <ian.campbell@xxxxxxxxxx> # Date 1300213246 0 # Node ID c426a7140c9923deefa9446f82fb96961f289616 # Parent d4ca456c0c25c3c3daedc216c657296f2895482a libxl: Make all hidden/static functions take a gc not a ctx Also ensure that static and hidden functions use the libxl__ prefix not just libxl_ (in the case of static functions only when they use a libxl prefix to start with). This follows the policy described in libxl.h "libxl memory management".
