Function Documentation

uel_conditional_apply()

void* uel_conditional_apply	(	uel_conditional_t *	conditional,
		void *	params
	)

Applies a conditional do some input.

This function takes some input and submits it to the test closure, whose output will be cast to a boolean value. According to this value, either if_true or if_false closures will be called with the same value as parameters.

Parameters

conditional	The conditional to be applied
params	The parameter that will be tested and provided to the chosen closure

Returns

Whatever the invoked closure returned

uel_conditional_init()

void uel_conditional_init	(	uel_conditional_t *	conditional,
		uel_closure_t	test,
		uel_closure_t	if_true,
		uel_closure_t	if_false
	)

Initialises a conditional structure.

Parameters

conditional	The conditional object to be initialised
test	The closure to test the input in order to decide what to do next
if_true	The closure to be invoked when the test closure returns true
if_false	The closure to be invoked when the test closure returns false
