* Modify the implementation of libc semaphores so that they can beDaniel Eischen2004-02-031-146/+132
| | | | | | | | | | | | | | | overridden by the threads library to provide a userland version of non-pshared semaphores and cancellation points. Also add a sem_timedwait(). The libc version of semaphores always uses kernel semaphores regardless of whether pshared is set or not. When threads are not present, it is difficult to get sem_wait() or sem_timedwait() to do the right thing (since pthread_cond_timedwait() and pthread_cond_wait() are stubs in libc and just return immediately).

The digit before the hexadecimal-point is never 0 unless the number itself is 0. o Clarify that the exponent field represents a decimal exponent of 2. o Discuss the fact that multiple valid representations are possible. o Remove the entry in the BUGS section claiming that %[aA] is not implemented. - Remove the entry in the BUGS section claiming that the ' flag for printing thousands separators is unimplemented for floating-point. - Remove the entry in the BUGS section claiming that the L modifier reduces the precision to "double" before conversion.

* Clarify the behavior of ptrace(2) a little bit: the tracing processRobert Watson2004-01-101-0/+24
| | | | | | | | | | | | | | | | | | must first attach to the traced process. If the tracing process exits without detaching, the traced process will be killed rather than continued. For the duration of the tracing session, the traced process is reparented to the tracing process (with resulting expected behaviors). It is permissible to trace more than one other process at a time. When using waitpid() to monitor the behavior of the traced process, signals are intercepted: they may optionally then be forwarded using ptrace(). Signals are generated normally by and for the process, but also by the tracing facility (SIGTRAP). Product of: Suffering Sponsored by: DARPA, AFRL Notes: svn path=/head/; revision=124346
