Macros
#define	y_breadcrumb_reset()   lr_save_string("", "breadcrumb")
	Resets the breadcrumb Use this macro to start a new breadcrumb or to reset an existing one. More...
#define	y_delay_once(delay_in_seconds)
	Delay for delay_in_seconds seconds, once. This macro will put the code to sleep for the specified amount of seconds, but only the first time the current position in the code is reached. If you use this in more than one place each of the calls will sleep exactly once. More...

Functions

int	y_rand_in_sliding_window (int lowerbound, int upperbound, int rand_max)
	Generate random number and test if it lies between 2 given boundaries. More...
int	y_rand_between (int lowerbound, int upperbound)
	Create a random number between two boundaries. (the boundaries are included!) More...
int	y_save_attribute_to_parameter (char *attrib, char *param)
	Fetch attribute from vUser's command line and store it in a parameter. This will fetch an attribute from the vUser's command line (as set in the scenario or in runtime settings as additional attributes) and stores it in the given parameter. More...
int	y_save_attribute (char *param)
	Fetch attribute from vUser's command lin and store it in a parameter of the same name. This will fetch an attribute from the vUser's command line (as set in the scenario or in runtime settings (addition attributes)) and stores it in a parameter of the same name. This function is a shortcut to y_save_attribute_to_parameter() More...
