Subject: manpages-dev: Bind man page does not document EADDRINUSE, does document ENOENT
Package: manpages-dev
Version: 2.17-1
Severity: normal

bind() lists AF_UNIX error codes, but doesn't list EADDRINUSE (unix(7)
does). It lists ENOENT, which I'm not sure can ever happen?

Versions of packages manpages-dev depends on:
ii manpages 2.17-1 Manual pages about using a GNU/Lin

manpages-dev recommends no packages.

It can, with AF_UNIX sockets.

Ah, non-existent dir in path. Makes sense, thanks!
