If you search the web under 'threads', you will eventually find a SunMicroSys location that has a number of examples of threaded code. One of these examples a 'tgrep' which is a multi-threaded grep. It is used as a testbed for different threading implementations. This might be a good test for the people who want to put in kernel threads. There is also a set of files there that convert POSIX threads to Solaris threads. ---from the README ---- Utility: tgrep (threaded recursive grep) Author: Ron Winacott Email: ronw@canada.sun.com Phone: (905) 477-0437 X 340 Or (1-800) 363-6200 Fax: (905) 477-0217 Address: 140 Renfrew Drive, Suite #206, Markham Ontario, Canada. L3R 6B3 Group: Developers Support Center (SMCC) OpCom. *Introduction. Tgrep is a multi-threaded version of grep. Tgrep supports all but the -w (word search) options of the normal grep command, and a few options that are only avaliable to tgrep. The real change from grep, is that tgrep will recurse down through sub-directories and search all files for the target string. Tgrep searches files like the following command: ------------------------------- ==================================================== Rip Toren | The bad news is that C++ is not an object-oriented | rpt@miles.sso.loral.com | programming language. ....
