# RES_* macros take a name, a count and an optional alignment.
|
||
|
|
# The count in in terms of the base size of the macro, and the
|
||
|
|
# default alignment is the base size.
|
||
|
|
# The macros are:
|
||
|
|
# Macro Base size
|
||
|
|
# RES_B 1
|
||
|
|
# RES_W 2
|
||
|
|
# RES_D 4
|
||
|
|
# RES_Q 8
|
||
|
|
# RES_DQ 16
|
||
|
|
# RES_Y 32
|
||
|
|
# RES_Z 64
|
||
|
|
#
|
||
|
|
# RES_U defines a union. It's arguments are a name and two or more
|
||
|
|
# pairs of "size, alignment"
|
||
|
|
#
|
||
|
|
# The two assigns are only needed if this structure is being nested
|
||
|
|
# within another. Even if the assigns are not done, one can still use
|
||
|
|
# STRUCT_NAME_size as the size of the structure.
|
||
|
|
#
|
||
|
|
# Note that for nesting, you still need to assign to STRUCT_NAME_size.
|
||
|
|
#
|
||
|
|
# The differences between this and using "struc" directly are that each
|
||
|
|
# type is implicitly aligned to its natural length (although this can be
|
||
|
|
# over-ridden with an explicit third parameter), and that the structure
|
||
|
|
# is padded at the end to its overall alignment.
