If a terminated process was created by an execve(2), the name of the executed file (at most ten characters of it) is saved in the field ac_comm and its status is saved by setting one of more of the following flags in ac_flag: AFORK, ACOMPAT, ACORE and ASIG. ASU is no longer supported. ANVER is always set in the above structure.
