Go4Expert - thread problem

I have created 2 thread In one thread iam reading data through serial.once it read it will go to the second thread.But It seems it never comes out of the first thread itself(read_gps).

my program goes like this

Code:

void CScenGenDoc::OnControlSerialin()

{

        upwin=true;        

        LPVOID param= NULL;

        LPVOID para=NULL;

        int a;

        

 GPS_READ =::CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)read_gps(),(LPVOID) param, 0,NULL);

  GPS_PARSE =::CreateThread(NULL, 0,(LPTHREAD_START_ROUTINE)frameparse(),(LPVOID) para, 0,NULL);

        

}

Code:

int read_gps()

{

while(1)

{

bool read=true;

}

}

Code:

int frameparse()

{

while(1)

{ 

if(read==true)

{
