Many of the interfaces described in the X/Open System Interfaces and Headers Specification (see reference XSH) are directly or indirectly concerned with accessing files stored on the system's file system. This appendix identifies those interfaces which may operate differently when used with XNFS.
For a complete list of the non-NFS related errors, as well as the mechanism by which a process can ascertain an error return code, see Section 2.3, Error Numbers in the X/Open System Interfaces and Headers Specification (see reference XSH).

It should be noted that the functions which provide inter-process communications via message queues, shared memory and semaphores all use a key_t to generate the corresponding inter-process communication channel. Objects of type key_t are not transferable between different systems and inter-process communications associated with these keys are not available across an NFS system.
The following functions have semantic differences over XNFS:

Where the semantic difference described only applies to the XNFS Issue 3W Specification this is identified by shading of the appropriate text. Semantic differences which do not contain this code marking are applicable to both XNFS Issue 3 and XNFS Issue 3W Specifications.
