Do those platforms not have fdopen(3) with the same "b" semantics? I note fdopen(3) is a POSIX thing, and "b" has no effect on POSIX systems, so perhaps not. Worth a look though? Failing that, you could fstat(3) the 2 open files and compare their st_ino and st_dev fields for equality before writing anything to either of them. -- Aaron Jones _______________________________________________ openssl-dev mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-dev
