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.

Macro Definition Documentation

APR_ALIGN

#define APR_ALIGN	(		size,
			boundary )

Value:

(((size) + ((boundary) - 1)) & ~((boundary) - 1))

Finding offsets of elements within structures.

Parameters

s_type	structure type name
field	data field within the structure

Returns

offset Alignment macros

APR_ALIGN_DEFAULT

#define APR_ALIGN_DEFAULT

(

size

)

Value:

APR_ALIGN(size, 8)

Default alignment

APR_ASCII_BLANK

#define APR_ASCII_BLANK   '\040'

FALSE TRUE a space

APR_ASCII_CR

#define APR_ASCII_CR   '\015'

a carrige return

APR_ASCII_LF

#define APR_ASCII_LF   '\012'

a line feed

APR_ASCII_TAB

#define APR_ASCII_TAB   '\011'

a tab

APR_OFFSET

#define APR_OFFSET	(		p_type,
			field )

Value:

((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

memmove

#define memmove	(		a,
			b,
			c )

Value:

bcopy(b,a,c)

String and memory functions
