2010-10-22sleep: check "SIGCHLD is SIG_IGN'ed" first. Saves two syscalls in common caseDenys Vlasenko

2010-10-22sleep: remove commented-out code. no code changesDenys Vlasenko
It can be easily reconstructed, since it's obvious Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com>
2010-10-21sleep: code shrinkDenys Vlasenko
Use less stack by using same "sigset_t set" object for new and saved signal set, remove redundant clearing of set, and do not save/restore errno around sigprocmask(SIG_SETMASK) - it never changes it. While at it, improve comments and make code style consistent across sleep.c file. text data bss dec hex filename - 242 0 0 242 f2 libc/unistd/sleep.o + 197 0 0 197 c5 libc/unistd/sleep.o Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com>
2010-09-15libc: Fix cancellation handling in some C functionsSalvatore Cro
According to POSIX.1-2008 standard, the following syscalls shall be cancellation points : waitid, sleep, fdatasync, ppoll. Further, if generic syscall is not available and stubs are configured, provide the stub implementation for function.

2009-09-15daemon: fix up INTERNAL_SYSCALL() usageMike Frysinger
Make sure we declare the error properly in case a port uses it, and fix the invocation of exit(). Since clone() will be returning a pid, assume that the value will not have the MSB set (negative) to simplify the error test a bit more. If gcc supports it, force this function to always be heavily optimized in a bid to avoid stack usage as much as possible.

2009-08-04Fix daemon build for no-MMU no-threads.Joseph Myers
CLONE_VM (used in no-MMU daemon) is defined in <bits/sched.h>. A build with threads ends up including <sched.h> via <pthread.h> via <bits/uClibc_mutex.h>; this indirect include does not happen for a build without threads, so this patch adds a direct <sched.h> include.
