Detailed Description

This is collection of oddballs that didn't fit anywhere else, and might move to more appropriate headers with the release of APR 1.0.

#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

Returns:

offset

Definition at line 95 of file apr_general.h.

#define APR_OFFSETOF	(		s_type,
			field
	)		APR_OFFSET(s_type*,field)

Finding offsets of elements within structures.

Parameters:

s_type	structure type name
field	data field within the structure

Returns:

offset
