To examine a directory that has a .mf file, go to the <work_dir>/build-IOM/src/os/iom/sys/sys/lib/gen directory. List the contents of the common.mf file:
... C__SRCS = \ insremque.c ovbcopy.c memstat.c iomRqTask.c util.c
The .mf files contain the definition of variables and nothing else. These variables are listed in Table 4-5.
