NAME
libcpc - CPU performance counter library
SYNOPSIS
cc [ flag... ] file... -lcpc [ library... ]
DESCRIPTION
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).
