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.
