musl/src/misc/openpty.c, branch master musl - an implementation of the standard library for Linux-based systems block pthread cancellation in openpty function 2014年12月21日T04:38:25+00:00 Rich Felker dalias@aerifal.cx 2014年12月21日T04:38:25+00:00 1227e418eafbbe55e74eee5d2b1e6e53a60102cd being a nonstandard function, this isn't strictly necessary, but it's inexpensive and avoids unpleasant surprises. eventually I would like all functions in libc to be safe against cancellation, either ignoring it or acting on it cleanly.

don't write openpty results until success is determined 2014年12月21日T04:22:57+00:00 Rich Felker dalias@aerifal.cx 2014年12月21日T04:22:57+00:00 3b26a32df42092af6d0cdac655e52635b91d36b2 not only is this semantically more correct; it also reduces code size slightly by eliminating the need for the compiler to assume the possibility of aliasing.
