cpc_open(3CPC) 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 subsequent libcpc func- tion calls. The cpc_open() function takes an interface version as an argument and returns NULL if that version of the interface is incom- patible with the libcpc implementation present on the system. Usually, the argument has the value of CPC_VER_CURRENT bound to the applica- tion 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 recompiled 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. ATTRIBUTES
