This week’s APIs by Example will focus on the concept of path name format in general and the character data conversion required to resolve the path name in particular. As we all know, object and library names uniquely identify an object in the QSYS.LIB file system. But for APIs to identify objects through the IFS interface, a path name is instrumental. The path name format is a data structure that contains the path name as well as information about the character set of the path name.
