Hi Seanb,

Thanks for your support.

I have tried to implement the nw_pthread_create instead of pthread_create
for sdio thread.

Source code:
    pthread_attr_init(&pattr);
    pthread_attr_setschedpolicy(&pattr,SCHED_RR);
    param.sched_priority = priority;
    pthread_attr_setschedparam(&pattr,¶m);
    pthread_attr_setinheritsched(&pattr, PTHREAD_EXPLICIT_SCHED);
    pthread_attr_setdetachstate(&pattr, PTHREAD_CREATE_DETACHED);
    pthread_attr_setstacksize(&pattr, SD_THREAD_STACK_SIZE);
#if QNX_THREAD
    if((status = pthread_create(&pHandle->osThreadId,(const pthread_attr_t
*)&pattr,
    (Qnx_Thread_Function)pFunction,pContext)) != SD_SUCCESS)
   {
        sd_Error("Could not create Thread - Tx err: %u\n",status);
     SD_FREE(pStackStart);
        return (SD_ERROR_INVALID);
    }
#else
    if((status = nw_pthread_create(&pHandle->osThreadId,(const
pthread_attr_t *)&pattr,
    (Qnx_Thread_Function)pFunction,pContext,0,NULL,NULL)) != SD_SUCCESS)
   {
        sd_Error("Could not create Thread - Tx err: %u\n",status);
     SD_FREE(pStackStart);
        return (SD_ERROR_INVALID);
    }
#endif
But It returns error No. 22

Please let me know if any example source code to implement the
nw_pthread_create() function.

Best Regards,
Saravana
