System Calls

System calls command line utilties for Linux and all POSIX based operating systems. Allows direct command line access to many popular kernel system calls in text format. Makes a great internals teaching tool for operating systems.

This utility makes the "sysconf", "pathconf", and "strconf" POSIX system calls available on the command-line. Report sysconf, pathconf, and confstr system variables. Variable names from the sysconf(3) call start with ``_SC. Variable names from the pathconf(3) call start with ``_PC. Variable...
