tcp_address_from_shell()
     #include "tcp.h"
     
     int tcp_address_from_shell(Host1, UserId, ServerFile, Port, Host)
         char *Host1;
         char *UserId;
         char *ServerFile;
         int *Port;
         char **Host;
     

This is identical to tcp_address_from_file(), except that, instead of relying on a network transparent file system to be able read ServerFile, it executes a remote shell command to Host1 to read the contents of the file. This is useful for applications that cannot rely on the presence of a network transparent file system.

*Host is a pointer to static storage that will be overwritten at the next call to tcp_address_from_shell().

The UserId argument may be specified as "", meaning login as myself. It is provided so that the machine that has the handle file need not have an account for every user that wishes to access it.

Note that Host1 need not be the same string as *Host, but typically is.

tcp_address_from_shell() returns zero upon successful completion.
