Re: [lwip-users] What IDE do you use now?

[伍瑞卿]

VC can not  parse the test.dsw from contrib-1.3.0.zip ,it should be converted with the following steps:

   1) open original test.dsw from contrib-1.3.0.zip  by wordpad.exe on Windows 、

   2）new a blank text file named test.dsw,and open it by notepad.exe

   3)   copy all content form  original test.dsw to  new text file test.dsw.

   4)  save new test.dsw ,and replace the original test.dsw ,

   5） reopen test.dsw

ok!

Dear Sir:

    I get contrib-1.3.0.zip, and unzip this zip file in lwip-1.3.0 directory, the directory struct is

lwip-1.3.0

  |-contrib    (Lwip-1.3.0 porting)

  |-doc

  |-src        (Lwip-1.3.0 source code)

    I use vc6 now, but i can not open the lwip-1.3.0\contrib\ports\win32\msvc6\test.dsw. Every time I try to open this dsw in vc6, every time nothing happened.

    Which IDE do you use now?

Thanks.

////////////////////////////////////////////////////////////////////////////////////////////////////

 

here is pppCLose() source code,in my code is  pc->linkStatusCB=NULL,so it while wait for PHASE_DEAD

 

/* Close a PPP connection and release the descriptor.
 * Any outstanding packets in the queues are dropped.
 * Return 0 on success, an error code on failure. */
int
pppClose(int pd)
{
  PPPControl *pc = &pppControl[pd];
  int st = 0;

 

  /* Disconnect */
#if PPPOE_SUPPORT
  if(pc->ethif) {
    PPPDEBUG((LOG_DEBUG, "pppClose: unit %d kill_link -> pppStopCB\n", pd));
    pc->errCode = PPPERR_USER;
    /* This will leave us at PHASE_DEAD. */
    tcpip_callback(pppStopCB, (void*)pd);
  } else
#endif /* PPPOE_SUPPORT */
  {
#if PPPOS_SUPPORT
    pc->kill_link = !0;
    pppMainWakeup(pd);
#endif /* PPPOS_SUPPORT */
  }

 

  if(!pc->linkStatusCB) {  
    while(st >= 0 && lcp_phase[pd] != PHASE_DEAD) {
      sys_msleep(500);
      break; //why this break? can i remove it?
    }
  }

 

  return st;
}
