函数名: farmalloc

功 能: 从远堆中分配存储块

用 法: void far *farmalloc(unsigned long size);

程序例:

#include <stdio.h>

#include <alloc.h>

#include <string.h>

#include <dos.h>

int main(void)

{

char far *fptr;

char *str = "Hello";

/* allocate memory for the far pointer */

fptr = farmalloc(10);

/* copy "Hello" into allocated memory */

/*

Note: movedata is used because we might

be in a small data model, in which case

a normal string copy routine can not be

used since it assumes the pointer size

is near.

*/

movedata(FP_SEG(str), FP_OFF(str),

FP_SEG(fptr), FP_OFF(fptr),

strlen(str) + 1);

/* display string (note the F modifier) */

printf("Far string is: %Fs\", fptr);

/* free the memory */

farfree(fptr);

return 0;

}
