hSemGate信号量

void llEnter()
{
    Error_Block eb;

    // If we don't have our semaphore yet, allocate one with "1" entry
    if( !hSemGate )
    {
        if( !(hSemGate = Semaphore_create( 1, 0, &eb )) )
        {
            DbgPrintf(DBG_ERROR,"Could not create llEnter() semaphore");
            return;
        }
    }

    // Wait on entering the stack.
    Semaphore_pend( hSemGate, (UINT32) ti_sysbios_BIOS_WAIT_FOREVER );

    // If case something goes wrong with the semaphore, track
    // problems entering the stack
    if( InKernel )
        DbgPrintf(DBG_ERROR,"Illegal call to llEnter()");

    InKernel=1;
}

请问，NDK里的recvnc()里调用的IIEnter()里的hSemGate信号量在哪产生的？谢谢！！！
