Speex dev - Sep 2009 - The speex encoding function can't normally work with the "SPEEX_SET_PLC_TUNING" Codec Option being set on?

The speex encoding function can't work with the 
"SPEEX_SET_PLC_TUNING"  Codec Option being set on?

Below is a command line of the  encoding Initialization function in my program?

bool speexEncode::Init(int quality,int bandmode,int &framesize)
{
...........// other command lines 

if(0==bandmode)
{//0==??
   this->m_EncState = speex_encoder_init(&speex_nb_mode);
   this->sample_rate=8000;
}
else if(1==bandmode)
{//1=??
this->m_EncState= speex_encoder_init(&speex_wb_mode);
this->sample_rate=16000;
}
else if(2==bandmode)
{//2==???
this->m_EncState= speex_encoder_init(&speex_uwb_mode);
this->sample_rate=32000;
}

int tmp =30 ; // set on the Packet Loss Compensation 
speex_encoder_ctl(this->m_EncState, SPEEX_SET_PLC_TUNING, &tmp);
   .......
   
   .......
 return true;
 }

 where  m_EncState is a Speex Encoder state.

 While I didn't set the   Codec Options  Codec Option, the speex encode
function   "int ret=
speex_encode_int(this->m_EncState,this->psClean,&m_bits)" return
a value that's bigger than zero. While  the Codec Options  Codec Option was
set on, 'int ret=
speex_encode_int(this->m_EncState,this->psClean,&m_bits)"  always
return zero,I was puzzled.Who can tell me why ? Thank you
