* On socket-only systems, fromhost() is nothing but an alias for the
|
|
* socket-specific sock_host() function.
|
|
*
|
|
* On systems with sockets and TLI, fromhost() determines the type of API
|
|
* (sockets, TLI), then invokes the appropriate API-specific routines.
|
|
*
|
|
* Diagnostics are reported through syslog(3).
