Currently madvise() appears only as an alias in cygwin.din:
madvise = posix_madvise SIGFE But according to the man pages, the error handling should differ: https://man7.org/linux/man-pages/man2/madvise.2.html: "On error, it returns -1 and errno is set to indicate the error." https://man7.org/linux/man-pages/man3/posix_madvise.3.html "On failure, it returns a positive error number." https://pubs.opengroup.org/onlinepubs/009695399/functions/posix_madvise.html https://pubs.opengroup.org/onlinepubs/9799919799/functions/posix_madvise.html "... otherwise, an error number shall be returned to indicate the error." The POSIX variant implies that 'errno' is left unchanged. On Cygwin, only posix_madvise() works as documented. On Linux, both functions work as documented. -- Regards, Christian -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
