#

# Subtle combination of files and libraries make up the C++ runtime system for

# kernel modules. We are dependant on the KernelModule kmod.make and

# CreateKModInfo.perl scripts to be exactly instep with both this library

# module and the libkmod module as well.

#

# If you do any maintenance on any of the following files make sure great

# care is taken to keep them in Sync.

# extenTools/KernelModule.bproj/kmod.make

# extenTools/KernelModule.bproj/CreateKModInfo.perl

# IOKitUser/kmodc++/pure.c

# IOKitUser/kmodc++/cplus_start.c

# IOKitUser/kmodc++/cplus_start.c

# IOKitUser/kmodc/c_start.c

# IOKitUser/kmodc/c_stop.c

#

# The trick is that the linkline links all of the developers modules.

# If any static constructors are used .constructors_used will be left as

# an undefined symbol. This symbol is exported by the cplus_start.c routine

# which automatically brings in the appropriate C++ _start routine. However

# the actual _start symbol is only required by the kmod_info structure that

# is created and initialized by the CreateKModInfo.perl script. If no C++

# was used the _start will be an undefined symbol that is finally satisfied

# by the c_start module in the kmod library.

#

# The linkline must look like this.

# *.o -lkmodc++ kmod_info.o -lkmod
