Static Directory Program
Note that several C library header files (12) are included to support the system calls
in build_files(). The build_files() function uses two defines (16) generated by
GDMOC.
8. Each entry (file name) is made available for management. The third parameter of
this mgmt_new_instance() call points to the filled-in structure holding file names.
Because each entry is individually registered with mgmt_new_instance(), the run-
time library can handle all the ordering and locating operations required when
processing SNMP requests.
9. Incoming SNMP requests are processed as they arrive until connection with the
NonStop agent is lost.
