# man -s 3CPC cpc_open Reformatting page. Please Wait... done CPU Performance Counters Library Functions cpc_open(3CPC) NAME cpc_open, cpc_close - initialize the CPU Performance Counter library SYNOPSIS cc [ flag... ] file... -lcpc [ library... ] #include <libcpc.h> cpc_t *cpc_open(int vers); int cpc_close(cpc_t *cpc); DESCRIPTION The cpc_open() function initializes libcpc(3LIB) and returns an identifier that must be used as the cpc argument in sub- sequent libcpc function calls. The cpc_open() function takes an interface version as an argument and returns NULL if that version of the interface is incompatible with the libcpc implementation present on the system. Usually, the argument has the value of CPC_VER_CURRENT bound to the application when it was compiled. The cpc_close() function releases all resources associated with the cpc argument. Any bound counters utilized by the process are unbound. All entities of type cpc_set_t and cpc_buf_t are invalidated and destroyed. RETURN VALUES If the version requested is supported by the implementation, cpc_open() returns a cpc_t handle for use in all subsequent libcpc operations. If the implementation cannot support the version needed by the application, cpc_open() returns NULL, indicating that the application at least needs to be recom- piled to operate correctly on the new platform and might require further changes. The cpc_close() function always returns 0. ERRORS These functions will fail if: EINVAL The version requested by the client is incompatible with the implementation.
