// Class libo4 is a C++ wrapper around the libo4 porting library. It handles // basic stuff like dynamic loading, library initialization etc. // The libo4 porting library is a set of functions that bridge from the AIX // runtime environment on OS/400 (aka PASE layer) into native OS/400 // functionality (aka ILE layer) to close some functional gaps that exist in // the PASE layer.

// Triggers cleanup of the libo4 porting library. staticvoid cleanup();
// Returns a number of memory statistics from OS/400. // // See libo4.h for details on this API. // // Specify NULL for numbers you are not interested in. // // Returns false if an error happened.
