Open Systems (QOpenSys) File System

The Open Systems (QOpenSys) file system is designed to be compatible with UNIX-based open system standards, such as POSIX and XPG. Like the root (/) file system, it takes advantage of the stream file and directory support provided by the integrated file system. In addition, it supports case-sensitive object names.

User Access

QOpenSys can be accessed only through the integrated file system interface. You work with QOpenSys using integrated file system commands, user displays, or ISO stream I/O functions and system APIs.

Path Names

Unlike the QSYS.LIB, QDLS, QLANSrv, and root (/) file systems, the QOpenSys file system distinguishes between uppercase and lowercase characters when searching object names.

The path names, link support, commands, displays and ISO stream I/O functions and system APIs are the same as defined under the root (/) file system.
