One is tempted to use pselect() to temporarily unblock the signals while waiting. This has two problems, though: one, pselect() is emulated in libc with older kernels, and this emulation has an (unavoidable) race. Two, I think pselect() will deliver the signal in addition to returning, which we want to avoid. Not sure about this though. -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
