Programming with the CommKit Function Library

CommKit Software Function Library

You can create a CommKit-capable application by calling the single

CommKit function dkdial(). The dkdial() function returns a ﬁle descriptor

that you can use in read(), write(), and close() calls.

To compile and link a program that uses the CommKit functions, use a

command like this one:

# cc -o

outputFileName sourceFileName

-ldk

If you want to create a 64-bit application, add the compiler option +DD64 to

the command above.

For more information on the CommKit software functions, refer to the

manual pages, which are available online and also in Appendix E,

“CommKit Manual Pages”.
