Hello, intro(2) manual says, also http://pubs.opengroup.org/onlinepubs/9699919799/ that EOVERFLOW should be defined.
-snip- #define _XOPEN_SOURCE 700 #include <sys/mman.h> #include <errno.h> int main() { errno = EACCES; errno = EAGAIN; errno = EBADF; errno = EINVAL; errno = EMFILE; errno = ENODEV; errno = ENOMEM; errno = ENOTSUP; errno = ENXIO; errno = EOVERFLOW; } -snip- I found that EOVERFLOW is actually found from headers under _BSD_VISIBLE, but this may indicate bug from mmap() Is this known issue? Btw is there bugzilla or some other bug tracking system where I can check my findings?
