Question: Compare FP_SEG And FP_OFF.Answer: Sometimes while working with far pointers we need to break a far address into its segment and offset. In such situations we can use FP_SEG and FP_OFF macros. Following program illustrates the use of these two macros.#include main( ) { unsigned s, o ; char far *ptr = "Hello!" ; s = FP_SEG ( ptr ) ; o = FP_OFF ( ptr ) ; printf ( "n%u %u", s, o ) ; } |
