公司vc培训的时候,给大家几个例子,比较实用,拿来分享

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
#include<malloc.h>

void main()
{
	unsigned char huge *array;
	long size;
	size = 8000000;
#ifdef _MSC_VER
	while((array = (unsigned char huge *) halloc(size,1)) == NULL)
#else
	while((array = (unsigned char huge *) farmalloc(size)) == NULL)
#endif
		size -= 100;
#ifdef _MSC_VER
	hfree(array);
#else
	farfree(array);
#endif
	printf("Largest Allocatable Block is %ld Bytes\n",size);
	getch();
	return;
}
