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
