libpctx(3LIB) Interface Libraries libpctx(3LIB)NAMElibpctx - process context library
SYNOPSIS
cc [ flag... ] file... -lpctx [ library... ]
DESCRIPTION
Functions in this library provide a simple means to access the underly‐
ing 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.
