编译运行吋，Process32First()出错。
这是书上的源码(见下）, 用masm编译时出错ProcessList.obj : error LNK2001: unresolved external symbol _Process32First@8
ProcessList.obj : error LNK2001: unresolved external symbol _Process32Next@8
ProcessList.exe : fatal error LNK1120: 2 unresolved externals
NMAKE : fatal error U1077: 'C:\masm32\bin\Link.EXE' : return code '0x460'
Stop.
查阅了一下网上，有人说需要初始化sizeof（Process32First）为dwSize:
http://msdn.(v=vs.85).aspx
dwSize
The size of the structure, in bytes. Before calling the Process32First function, set this member to sizeof(PROCESSENTRY32). If you do not initialize dwSize, Process32First fails.
但是，在汇编语言里怎样实现？
补充一下， 在kernel32.inc是这样定义的:
Process32FirstW PROTO STDCALL :DWORD,:DWORD
IFDEF __UNICODE__
Process32First equ <Process32FirstW>
ENDIF
Process32NextW PROTO STDCALL :DWORD,:DWORD
IFDEF __UNICODE__
Process32Next equ <Process32NextW>
ENDIF
