可用于实现*。端口操作不需要编写驱动，在Win95/98下直接可以使用汇编的In/Out指令。VC中也提供了_inp/_outp这样的函数(QA001059 outportb、inportb对应的函数)。不过在NT下，不能使用In/Out指令，参考QA001296 如何在WindowsNT/2000下用VB6写硬件IO控制。 如果使用硬件中断就必须编写驱动，标准的办法是采用微软的DDK。Win98和WinNT 4.0/5.0的DDK可以从http://www.microsoft.c

Using Malloc in VB6 - In computing, malloc is a subroutine for performing dynamic memory allocation. This code shows how to create little chunks of memory completely independently of variables or classes, how to access their contents, reallocate them
