"near" and "far" pointers are actually non-standard
qualifiers that you'll find only on x86 systems. They
reflect the odd segmentation architecture of Intel
processors. In short, a near pointer is an offset only,
which refers to an address in a known segment. A far pointer
is a compound value, containing both a segment number and an
offset into that segment.

Segmentation still exists on Intel processors, but it is not
used in any of the mainstream 32-bit operating systems
developed for them, so you'll generally only find the "near"
and "far" keywords in source code developed for Windows 3.x,
MS-DOS, Xenix/80286, etc.

It is used to access the higher memory addresses.

Answer / peter

I think it's kind of pointer for different computer
architecture such as X86, IBM power server and so on because
various model of memory model is different.

Question: We would like to design and implement a programming solution to the reader-writer problem using semaphores in C language under UNIX. We assume that we have three readers and two writers processes that would run concurrently. A writer is to update (write) into one memory location (let’s say a variable of type integer named temp initialized to 0). In the other hand, a reader is to read the content of temp and display its content on the screen in a formatted output. One writer can access the shared data exclusively without the presence of other writer or any reader, whereas, a reader may access the shared memory for reading with the presence of other readers (but not writers).
