One external variable is initialized to a default value and may be changed as needed.
loglvl the log level of the messages written to the log file. The initial value of the variable is 6.
There are two external variables that must be set by the calling program or they will not be used. They are:
logf the return value of an fopen(3) library call of the file that will be used as the log file.
ctl_stat a pointer to a stat structure that was passed to the stat(2) system call for the common
channel device. The interface number of the common channel device must match the
interface number of the server.
