Code style / indentation------------------------The file indent-all.sh contains information about the current codestyle.  Run this script before commits.Variable argument macros------------------------Variable argument macros are non-portable in general, and should beavoided.  Either use a second set of parentheses like DEBUG, or createa variable argument function like error.Structure---------The core protocol stack should be system-independent (i.e. ANSI C89only) so that it is easy to port. This currently applies to thefollowing files:bitmap.c licence.c orders.c rdp.c rdp5.c cache.c iso.c mcs.csecure.c mppc.c channels.crdesktop.cCompiler support----------------The source code should be compatible with ANSI C89. One exception isthe SeamlessRDP ServerEXE and ClientDLL, which should be compatiblewith ANSI C99.RDP resources-------------http://dev.remotenetworktechnology.com/refdata.htmChecking for out of memory conditions-------------------------------------Try to handle out of memory conditions gracefully. Use the xmallocroutines from rdesktop.c, instead of calling malloc manually. Also,remember that several Xlib functions can return NULL. This includesXGetImage. Use exit_if_null to verify returned pointers.
