/*
  * 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).
