farcalloc

farcalloc是一個函式名，功 能是從遠堆疊中申請空間。

基本介紹

• 中文名：farcalloc
• 程式例：#include <stdio.h>
• 用  法：void far *farcalloc
• 功  能：從遠堆疊中申請空間

用法

void far *farcalloc(unsigned long units, unsigned ling unitsz);

程式例

#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 = farcalloc(10, sizeof(char));

/* copy "Hello" into allocated memory */

/*

Note: movedata is used because you

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));

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

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

/* free the memory */

farfree(fptr);

return 0;
