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

Finding offsets of elements within structures.

Parameters:

s_type	structure type name
field	data field within the structure

#define APR_STRINGIFY ( n ) APR_STRINGIFY_HELPER(n)

String and memory functions Properly quote a value as a string in the C preprocessor

#define APR_STRINGIFY_HELPER ( n ) #n

Helper macro for APR_STRINGIFY
