(tcp_listen, player_addrlen): New. IPv4-only code factored out of
player_init().
(player_init): Use them.
(player_accept): Address family independence.
(tcp_connect): New.
(main): Use it.
(hostaddr, hostconnect, hostport): Internal linkage.
(main): Clarify messages.
(hostport) [_WIN32]: Remove useless conditional code.
(main): Fall back to compiled-in host only if environment doesn't
supply one, not if it can't be resolved. Same for port.
thread entrypoints:
(lwpSelect, shutdown_sequence): Parameters didn't match thread entry
point prototype.
(lwpEntryPoint): Arguments didn't match thread entry point prototype.
Change linkage of functions without prototype declaration to static
where possible.
Remove some superflous declarations, replace others by suitable
includes.
effect. Replace calls by struct assignment where possible. Replace
clear buffer, copy string to buffer by strncpy(). Use assignment to
clear when that's clearer. Replace overlapping copy through bounce
buffer by memmove(). Replace rest by standard memset() and memcpy().
Also use sizeof() instead of literal array sizes for robustness, and
instead of symbolic array sizes for clarity.
