root/cebix/SheepShaver/src/include/xlowmem.h
Revision: 1.7
Committed: 2006-05-03T21:45:14Z (18 years, 6 months ago) by gbeauche
Content type: text/plain
Branch: MAIN
Changes since 1.6: +2 -0 lines
Log Message: 
Add patches for native GetNamedResource() and Get1NamedResource(). This will
be useful to fix a bug in the AppleShare extension (see DRVR .AFPTranslator
in Basilisk II)

Unrelated improvement: call sheepshaver_cpu::get_resource() directly, don't
get it through another global function.
