get_myaddress: ioctl (get interface configuration)
Explanation
The function get_myaddress(), which puts the local
host's IP address into addr, was unsuccessful because
of a negative return value received from the ioctl()
system call.  The ioctl() system call controls the operating
characteristics of sockets.

System action
The calling program ends.

Operator response
No action is needed.

System programmer response
Check for the correct entries declared in the s, cmd,
and arg parameters of the ioctl() system call
and the addr parameter of the get_myaddress()
call, check that the network interface configuration is defined in
an ifconf structure of the IF.H data set, and restart the
program. See the z/OS Communications Server: IP Programmer's Guide
and Reference for more information.
