* Use sigaction() instead of signal() to avoid pulling in unnecessaryguenther2015-10-251-3/+5
| | | | | | | wrappers. To keep uses from crawling back in, mark signal() as deprecated inside libc. ok deraadt@
* Merge the sigaction() and sigprocmask() overloads/wrappers from libpthreadguenther2015-10-231-4/+3
| | | | | | | | | into libc, and move pthread_sigmask() as well (just a trivial wrapper). This provides consistent handling of SIGTHR between single- and multi-threaded programs and is a step in the merge of all the libpthread overloads, providing some ASM and Makefile bits that the other wrappers will need. ok deraadt@ millert@

| | | | | | C standard are all weak. Apply __{BEGIN,END}_HIDDEN_DECLS to gdtoa{,imp}.h, hiding the arch-specific __strtorx, __ULtox_D2A, __strtorQ, __ULtoQ_D2A symbols.

* Per POSIX, fix raise() and abort() to send the signal to the current thread.guenther2012-11-101-3/+5
| | | | | | Should make coredumps from abort() easier to debug too. ok kurt@

* Call _exit() not exit() from abort() if we are unable to kill ourselvesmillert2004-01-201-3/+3
| | | | | to avoid flushing stdio twice. This code path should never really happen though. Also make the function declaration ANSI. OK deraadt@

* Add thread-safety to libc, so that libc_r will build (on i386 at least).d1998-11-201-1/+10
| | | | | | | | | | | | | All POSIX libc api now there (to P1003.1c/D10) (more md stuff is needed for other libc/arch/*) (setlogin is no longer a special syscall) Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS). Doc some re-entrant routines Add libc_r to intro(3) dig() uses some libc srcs and an extra -I was needed there. Add more md stuff to libc_r. Update includes for the pthreads api Update libc_r TODO
