2.为什么要调用CloseHandle

[cpp99]

1.这代码运行通不过
2.为什么要调用CloseHandle

int main(int argc, char *argv[])
{
HMODULE module = GetModuleHandle(0);
CHAR buf[MAX_PATH];
GetModuleFileName(module, buf, sizeof buf);
CloseHandle(HANDLE(4));
__asm {
lea eax, buf
push 0
push 0
push eax
push ExitProcess
push module
push DeleteFile
push UnmapViewOfFile
ret
}
return 0;
}

加#include <windows.h>就行了

This function closes an open object handle.
CloseHandle invalidates the specified object handle, decrements the object’s handle count, and performs object retention checks. After the last handle to an object is closed, the object is removed from the system. Persistent objects such as databases and files will remain in storage, but must be re-opened to be accessed again.

这涉及到操作系统中的引用问题，当系统分配一个handle后，其中的引用会自加1的，
你可以看看com技术，所以在用完了，要把handle给close掉。
