| 释义 | § 解释 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: movedatais 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; } |
