LIBCPC(3LIB) Interface Libraries LIBCPC(3LIB)

libcpc - CPU performance counter library

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

Functions in this library provide access to CPU performance counters on platforms that contain the appropriate hardware. A more detailed explanation of the library and a list of processor-specific events is available in cpc(3CPC).

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