What is huge pointer in c

Unlike to far pointer, this pointer which is fixed and hence that part of the sector in which they are located cannot be modified in any way; huge pointers can be. The pointer was seen to be somehow slow, but it allow its pointer to points out many segments with a clear and comparable way. In a near pointer, it uses offset data address in a segment default while a far pointer uses both sector data address and offset data address and it locates the data in the computer memory.

A far pointer is typically 32 bit that can access memory outside current segment. To use this, compiler allocates a segment register to store segment address, then another register to store offset within current segment.

Like far pointer, huge pointer is also typically 32 bit and can access outside segment. In case of far pointers, a segment is fixed.

In far pointer, the segment part cannot be modified, but in Huge it can be. Skip to content. Change Language. Related Articles. Save Article. Improve Article. Like Article.
