我在 OnW32DeviceIoControl(PIOCTLPARAMS pDIOCParams) 里面用 SHELL_LocalAlloc 分配内存竟然不成功!

switch (pDIOCParams->dioc_IOCtlCode)
{
case VXD_OPEN_PORT:
break ;
case VXD_CLOSE_PORT:
break ;
case VXD_EXEC_PROG:
{
DWORD rCode;
dout << \"Trying to Execute telnet.exe\" << endl;
PPVOID la;
WinExec.nCmdShow = 1;
WinExec.lpCmdLine = SHELL_LocalAllocEx(LPTR + LMEM_STRING,0,\"c:\\\\windows\\\\telnet.exe\",la);
if (WinExec.lpCmdLine==0)
sprintf((char*)pDIOCParams->dioc_OutBuf,\"%s\",\"Alloc Error!\");break;
rCode = SHELL_CallDll(\"KERNEL\",\"WINEXEC\",sizeof(WinExec),&WinExec);
SHELL_LocalFree(WinExec.lpCmdLine);

if (!rCode)
sprintf((char*)pDIOCParams->dioc_OutBuf,\"%s\",\"Finished Execute but failed!\");
else
sprintf((char*)pDIOCParams->dioc_OutBuf,\"%s\",\"Finished Execute successed!\");
}
 break;
}
return 0;
