NAME              fork -- spawn new process

SYNOPSIS          sys      fork      / fork = 2.
                  (new process return)
                  (old process return)

DESCRIPTION       fork is the only way new processes are created. The new
                  process's core image is a copy of that of the caller of
                  fork the only distinction is the return location and the
                  fact that r0 in the old process contains the process ID of
                  the new process. This process ID is used by wait.

SEE ALSO          sys wait, sys exec

DIAGNOSTICS       The error bit (c--bit) is set in the old process if a new
                  process could not be created because of lack of swap
                  space.

BUGS              See wait for a subtle bug in process destruction.
