我是要做个安装程序,首先安装mysql,我要判断mysql是否是正常安装完毕的。然后才能进行下一步的安装。
DWORD code;
GetExitCodeProcess( mysqlhandle, code);
GetLastError:
The return value is the calling thread's last-error code value. Functions set this value by calling the SetLastError function. The Return Value section of each reference page notes the conditions under which the function sets the last-error code.
我怎么知道mysql要返回什么呀?
