lbm_custom_type_create()

bool lbm_custom_type_create	(	lbm_uint	value,
		custom_type_destructor	fptr,
		const char *	desc,
		lbm_value *	result
	)

Create a value of a custom type with a destructor and a description

Parameters

value	The custom value. This can be a pointer to memory allocated on the C-side.
fptr	The destructor function. This function should free any memory allocated on the C-side.
desc	A description of the type that will be used for printing.
result	Pointer to lbm_value that will hold the value of the custom type.

Returns

true on success or false otherwise.

lbm_custom_type_destroy()

bool lbm_custom_type_destroy

(

lbm_uint *

lbm_mem_ptr

)

Called by garbage collector and invokes the destructor on the custom value.

/return true on success or false otherwise.
