  25 // Encapsulates the libperfstat library.
  26 //
  27 // The purpose of this code is to dynamically load the libperfstat library
  28 // instead of statically linking against it. The libperfstat library is an
  29 // AIX-specific library which only exists on AIX, not on PASE. If I want to
  30 // share binaries between AIX and PASE, I cannot directly link against libperfstat.so.

  41 //
  42 // Note: I define all structures as if I were to include libperfstat.h on an AIX 5.2
  43 // build machine.
  44 //
  45 // The ratio behind that is that if I would build on an AIX 5.2 build machine,
  46 // include libperfstat.h and hard-link against libperfstat.a, the program should
  47 // work without recompilation on all newer AIX versions.
