// Encapsulates the libperfstat library.

//

// The purpose of this code is to dynamically load the libperfstat library

// instead of statically linking against it. The libperfstat library is an

// AIX-specific library which only exists on AIX, not on PASE. If I want to

// share binaries between AIX and PASE, I cannot directly link against libperfstat.so.

// These are excerpts from the AIX 5.3, 6.1, 7.1 libperfstat.h -

// this is all we need from libperfstat.h and I want to avoid having to include <libperfstat.h>

//

// Note: I define all structures as if I were to include libperfstat.h on an AIX 5.2

// build machine.

//

// The ratio behind that is that if I would build on an AIX 5.2 build machine,

// include libperfstat.h and hard-link against libperfstat.a, the program should

// work without recompilation on all newer AIX versions.
