// This function switches control to the task switcher in a non-

//
//Description:
//
// This function starts the specified thread function.
//
//Parameters:
//
// fn_P = Pointer to the thread function
// param_P = Pointer to the thread function input parameter structure
//
//Return Value:
//
// 0 = Successfull
// non-zero = Failure, unable to start the thread
