LIBPCTX(3LIB) Interface Libraries LIBPCTX(3LIB)


NAME


libpctx - process context library

SYNOPSIS


cc [ flag... ] file... -lpctx [ library... ]


DESCRIPTION


Functions in this library provide a simple means to access the underlying
facilities of proc(4) to allow a controlling process to manipulate the
state of a controlled process.


This library is primarily for use in conjunction with the libcpc(3LIB)
library. Used together, these libraries allow developers to construct
tools that can manipulate CPU performance counters in other processes.
The cputrack(1) utility is an example of such a tool.
