Question: How do I write code that reads the segment register settings?
Answer: We can use segread( ) function to read segment register settings. There are four segment registersâ??code segment, data segment, stack segment and extra segment. Sometimes when we use DOS and BIOS services in a program we need to know the segment register's value. In such a situation we can use segread( ) function. The following program illustrates the use of this function.#include <dos.h> main( ) { struct SREGS s ; segread ( &s ) ; printf ( "nCS: %X DS: %X SS: %X ES: %X",s.cs, s.ds, s.ss, s.es ) ; } |
