enami 686e03f5e7 - If fktrace(2) failed, just exit rather than waiting for trace output.

christos 1e77a9474a Fix a bug in ktruss and ktrace, where they would randomly stop tracing if 
the write to the ktraced file descriptor (when they used fktrace internally)
would block. Fix by clearing the non-blocking bit in the file descriptor by
default, so that the writes will block. This has the side effect of stopping
the traced process. Add a flag to override (-n) this behavior and have the
trace stop without blocking the traced process (the previous behavior).
Fix lint, add checks to failed syscalls, ansify.

enami 698c01aba0 Fix usage: 
- ktrace(1) takes -s.
- ktruss(1) takes -l.
- -C/-c and commands are exclusive.
- make output fits 80 column.
 2004-02-28 02:22:31 +00:00
enami 8a1309b72f - Make ktruss(1) works as expected when -c or -C is specified. 
- Include pid or file descriptor in error message when
  ktrace(2)/fktrace(2) failed.
- Remove unnecessary cast.

dsl fde07830ad Grok KTR_EXEC_ENV and KTR_EXEC_ARG. 
Make ktrace -c default to removing all trace points (not just the default ones).
Make kdump default to dumping everything in the trace file.
Add 'A' (all) and '-' (remove following) to valid -t arguments.
Dump data block of UNKNOWN trace points in hex + ascii.
Make first time output with -R 0 (instead of time since epoch).
Use svis() instead of vis() to get " escaped (as \") (needs fixed libc)
Correctly pass unsigned values to svis()
Update man pages.
