some additional data.
AIX 6.1:
defined sun_path = 1023
max sun_path = 1023
i'll also point out the existence of the SUN_LEN() macro, which is
defined on all the previously mentioned operating systems, and which
calculates the size of a sockaddr_un structure using strlen() of
sun_path, not sizeof().
that said, as a counter argument, UNIX Network Programming by Richard
Stevens explicitly mentions that the use of sizeof() is ok.
still, personally, i think it's pretty risky for an OS to change this
definition. (it seems that AIX is the only OS i've seen that has done
so.) i say this because use of the sockaddr_un structure is so
prevalent. it's commonly embedded into other structures and passed
around via APIs that (unlike bind(), connect(), etc) don't take a size
parameter which specifies the size of the structure.
