What are near pointers in c?

Just forget it, it was a question twenty years ago when we worked in MS-DOS with a 16/20 bit CPU. Near pointers contain 16 bits, far pointers contain 32 bits (but only 1MB (or 1MB+65520 bytes) are really addressible).


How many bytes are read in pointers by pointers dereferencing?

When you dereference a pointer you "read" the number of bytes determined by the pointer's type. That is, a char pointer dereferences a single byte while an int pointer dereferences 4 bytes (assuming a 32-bit int) -- regardless of the type actually stored at that address. However, note that a pointer can only actually point at a single byte since it only has storage for a single memory address. How many additional bytes are dereferenced is entirely dependant on the type of the pointer. To determine how many bytes are actually allocated to an address, use the sizeof operator, passing a dereferenced pointer (the pointer must point at the start of the allocation). If the pointer points at several elements of the same type (an array), then divide the total bytes by the size of the pointer's type to determine the number of elements in the array.
