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