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 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.

INTERFACES
       The shared object libpctx.so.1 provides the public  interfaces  defined
       below.  See Intro(3) for additional information on shared object inter‐
       faces.

       pctx_capture		     pctx_create
       pctx_release		     pctx_run
       pctx_set_events

FILES
       /usr/lib/libpctx.so.1	    shared object

       /usr/lib/64/libpctx.so.1	    64-bit shared object
