Initialization Interfaces

An application preparing to use the CPC facility initializes the library with a call to the cpc_open() function. This function returns a cpc_t * parameter that is used by the other interfaces. The syntax for the cpc_open() function is as follows:


The value of the ver parameter identifies the version of the interface that the application is using. The cpc_open() function fails if the underlying counters are inaccessible or unavailable.
