of the missing functionality from procfs(4) and new functionality for monitoring and debugging specific processes. procstat(1) operates in the following modes: -b Display binary information for the process. -c Display command line arguments for the process. -f Display file descriptor information for the process. -k Display the stacks of kernel threads in the process. -s Display security credential information for the process. -t Display thread information for the process. -v Display virtual memory mappings for the process. Further revision and modes are expected. Testing, ideas, etc: cognet, sam, Skip Ford <skip at menantico dot com> Wesley Shields <wxs at atarininja dot org>
