The output() function sets the output gpio-pin to the defined state with a defined timeout.
int output(int pin,int state,int timeout)
Example:
void main()
{
output(1 ,1, 1000); /* output 1 to ON for 1000 ms */
output(1 ,0, 1000); /* output 1 to OFF for 1000 ms */
output(1 ,1, 0); /* output 1 to ON permanently */
}
