struct nfct_helper* nfct_helper_alloc

(

void

)

nfct_helper_alloc - allocate a new helper object

In case of success, this function returns a valid pointer, otherwise NULL s returned and errno is appropriately set.

const void* nfct_helper_attr_get	(	struct nfct_helper *	helper,
		enum nfct_helper_attr_type	type
	)

nfct_helper_attr_get - get one attribute the helper object

Parameters

nfct_helper	pointer to the helper object
type	attribute type you want to set

This function returns a valid pointer to the attribute data. If a unsupported attribute is used, this returns NULL.
