farcalloc

函数名: farcalloc

功 能: 从远堆栈中申请空间

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

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 = 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

", fptr);

/* free the memory */

farfree(fptr);

return 0;

}
