APIs for the UNIX-type environment

UNIX-type APIs, which include the socket APIs and the integrated file system APIs, support an open environment on the system.

The socket functions and the integrated file system reduce the amount of effort to move UNIX applications to the system.

The integrated file system is a function of the IBM i operating system that supports stream input/output and storage management similar to personal computers and UNIX operating systems. It also provides an integrating structure over all information stored on the system.

The naming conventions for the UNIX-type APIs are determined by industry standards organizations.
