Storage Specification for Pointers
To properly access near , far , and rom objects using a pointer, the compiler provides the
ability to associate the storage specifier with the pointer type:
•
near pointer
A near pointer points to near data.
•
far pointer
A far pointer points to far data.
•
rom pointer
A rom pointer points to ROM data.
For example:
char *p;/* p is a pointer to a :

near char : small model

far char : large model. */

char far *fp;/* fp is a pointer to a far char,

fp itself is stored in:

near memory for small model

far memory for large model. */

char far * far fpf;/* fpf is a pointer to a far
char,

fpf itself is stored in far
