#define APR_OFFSET	(	p_type,
		field
	)	((long) (((char ) (&(((p_type)NULL)->field))) - ((char ) NULL)))

Finding offsets of elements within structures. Taken from the X code... they've sweated portability of this stuff so we don't have to. Sigh...

Parameters

p_type	pointer type name
field	data field within the structure pointed to

Finding offsets of elements within structures.

Parameters

s_type	structure type name
field	data field within the structure

Value:

struct type { \
   incompletion \
   void *unk[]; \
};

Macro to provide a way to turn an incomplete type into a complete type containing common pointers for a provider.
