position. Especially the screen size, and potentially everything except the input state and attributes. Do this by changing the cursor position setting method to a general syncing method. Use proper constructors instead of copying to create kernel terminal contexts. We really want clones and not new instances, but there is no method for cloning and there is nothing in the active instance that needs to be cloned exactly. Add proper destructors for kernel terminal contexts. I doubt that the destructor code has every been reached, but if it was then it leaked the memory of the clones. Remove freeing of statically allocated memory for the non-kernel terminal context for the same terminal as the kernel. This is in the nearly unreachable code. This used to not happen because delicate context swapping made the user context use the dynamic memory and kernel context the static memory. I didn't restore this swapping since it would have been unnatural to have all kernel contexts except 1 dynamic. The constructor for terminal context has bad layering for reasons related to the bug. It has to return static memory early before malloc() works. Callers also can't allocate memory until after the first constructor selects an emulator and tells upper layers the size of its context. After that, the cloning hack required the cloning code to allocate the memory, but for all other constructors it would be better for the terminal layer to allocate and deallocate the memory in all cases. Zero the memory when allocating terminal contexts dynamically.

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
