Enumeration Type Documentation

enum signature_flags

signature flags Used internally for manage signature creation

For internal use only.

Enumerator:

EASYDBUS_SIGNATURE_NORMAL	normal signature
EASYDBUS_SIGNATURE_VARIANT	signature for variant elements

Function Documentation

struct easydbus_signature_elem_stack* easydbus_add_elem_to_stack	(	enum el_type	el,
		struct easydbus_signature_elem_stack *	stack
	)			[read]

Todo:

• manage complex data (ex. struct of struct, etc.)

For internal use only.

Parameters:

	el	element type to insert.
	stack	signature stack where insert element type.

Returns:

NULL on error

pointer to list with new elem;
