NAME
       cpc_version - coordinate CPC library and application versions

SYNOPSIS
       cc [ flag... ] file... -lcpc [ library... ]
       #include <libcpc.h>

       uint_t cpc_version(uint_t version);

       The  cpc_version()  function takes an interface version as an argument and returns an interface version as a result.  Usually, the argument
       will be the value of CPC_VER_CURRENT bound to the application when it was compiled.

       If the version requested is still supported by the implementation, cpc_version() returns the requested version number and  the  application
       can  use  the  facilities  of  the  library  on that platform.  If the implementation cannot support the version needed by the application,
       cpc_version() returns CPC_VER_NONE, indicating that the application will at least need to be recompiled to operate  correctly  on  the  new
       platform, and may require further changes.

       If version is CPC_VER_NONE, cpc_version() returns the most current version of the library.

       Example 1:  Protect an application from using an incompatible library.

       The following lines of code protect an application from using an incompatible library:

       if (cpc_version(CPC_VER_CURRENT) == CPC_VER_NONE) {
	       /* version mismatch - library cannot translate */
	       exit(1);
       }

       The  cpc_version()  function exists for binary compatibility only. Source containing this function will not compile. This function is obso-
       lete and might be removed in a future release. Applications should use cpc_open(3CPC) instead.

       The version number is used only to express incompatible semantic changes in the performance counter interfaces on the given platform within
       a  single  instruction  set  architecture, for example, when a new set of performance counter registers are added to  an existing processor
       family that cannot be specified in the existing cpc_event_t data structure.
