to be accepted. POSIX.1-2001 allows either error to be returned for
this case, and does not require these constants to have the same value,
so a portable application should check for both possibilities.
[ ] EBADF - The descriptor is invalid.
[i] ECONNABORTED - A connection has been aborted.
[I] EBADF - The descriptor is invalid.
[I] ECONNABORTED - A connection has been aborted.
[i] EFAULT - The addr argument is not in a writable part of the user address space.
[ ] EINTR - The system call was interrupted by a signal that was caught before a valid connection arrived; see signal(7).
[ ] EINVAL - Socket is not listening for connections, or addrlen is invalid (e.g., is negative).
[ ] EINVAL - (accept4()) invalid value in flags.
[ ] EMFILE - The per-process limit of open file descriptors has been reached.
[I] EMFILE - The per-process limit of open file descriptors has been reached.
[ ] ENFILE - The system limit on the total number of open files has been reached.
[ ] ENOBUFS, ENOMEM - Not enough free memory. This often means that the memory allocation is
limited by the socket buffer limits, not by the system memory.
[i] ENOTSOCK - The descriptor references a file, not a socket.
[i] EOPNOTSUPP - The referenced socket is not of type SOCK_STREAM.
[I] EOPNOTSUPP - The referenced socket is not of type SOCK_STREAM.
[ ] EPROTO - Protocol error.
