[ts-7000] Trying to encapsulate thread in class

["Richard" <>]

Ok here is my source code, the first section is the implementation,
the second section is the declaration, and the third is the compiler
error.  Any help on this would be appreciated.


/**********************  Implementation  **********************/
#include "WatchdogControl.h"
//Class Constructor, currently being used to set the default timer
watchdog.
WatchdogControl::WatchdogControl()
{
    timerValue = 0x07;
}

WatchdogControl::~WatchdogControl()
{
}

void WatchdogControl::startWatchdogMonitor()
{
    if (!WatchdogTimerOn);
    pthread_t WatchdogMonitorId;
    pthread_create (&WatchdogMonitorId, NULL, &resetWatchdog, NULL);
    WatchdogTimerOn = true;    
}

void* WatchdogControl::resetWatchdog(void* nothing)
{
   sleep(300);
   setWatchdogTimer(); 
   return NULL;
}

void WatchdogControl::setWatchdogTimer()
{
    int fd = open("/dev/mem", O_RDWR);
    assert(fd != -1);
    
    wdt_control = (unsigned char
*)mmap(0,getpagesize(),PROT_READ|PROT_WRITE,MAP_SHARED,fd,0x23800000);
    wdt_feed = (unsigned char
*)mmap(0,getpagesize(),PROT_READ|PROT_WRITE,MAP_SHARED,fd,0x23C00000);
    
    *wdt_feed = WATCHDOG_FEED_BYTE;
    *wdt_control = timerValue;
}
