-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 It seems like it would be pretty easy to add several new close-on-exec features required by POSIX 2008:
open(name, O_RDONLY | O_CLOEXEC); // skips the need to use fcntl fcntl(fd, F_DUPFD_CLOEXEC); // like F_DUPFD, but closes window without having to use // fcntl(fd, F_SETFD, fcntl(fd, F_GETFD)) and those provided by glibc as extensions: fopen(name, "re"); // like fopen "r", but with cloexec set The argument is that in multi-threaded apps, if one thread opens a file but has not yet turned on the close-on-exec bit while another thread does a fork-and-exec, then you leaked the fd into the child; and these new flags close the window. Should I go ahead and prepare a patch for the newlib side? - -- Don't work too hard, make some time for fun as well!
