Use integrated file system APIs in the QSYS.LIB file system

Many integrated file system APIs are valid in the QSYS.LIB file system.

The APIs listed in Perform operations using APIs can operate on the QSYS.LIB file system, except for the following restrictions:

File operations can be done only on program-described physical files and source physical files.
The symlink() function can be used only to link to an object in QSYS.LIB from another file system that supports symbolic links.
The QjoStartJournal() and QjoEndJournal() APIs cannot be used on database physical files.
