Function Documentation

cu_offset_t cuoo_layout_align ( cuoo_layout_t  layout  ) 

The alignment of layout in bytes, rounded upwards.

cu_offset_t cuoo_layout_bitalign ( cuoo_layout_t  layout  ) 

The alignment of layout in bits. This is 1 for bitfields, otherwise 8, 16, etc up to the word size.

cu_offset_t cuoo_layout_bitsize ( cuoo_layout_t  lyo  ) 

The number of bits needed to represent lyo.

void cuoo_layout_dump ( cuoo_layout_t  lyo,
FILE *  out 

Dump of lyo to out for debugging.

cuoo_layout_t cuoo_layout_pack_bits ( cuoo_layout_t  prefix,
cu_offset_t  bitsize,
cu_offset_t  bitalign,
cu_offset_t *  bitoffset 

The layout of prefix with bitsize bits aligned on bitalign bits packed inside or after. The bit-offset of the allocated bits is stored in *bitoffset.

bitalign must be 1 (bitfield), 8 (a byte), or a larger power of two.
cuoo_layout_t cuoo_layout_product ( cuoo_layout_t  lyo0,
cuoo_layout_t  lyo1,
cu_offset_t *  bitoffset 

The layout of lyo0 with lyo1 packed inside or appended.

cuoo_layout_t cuoo_layout_ptr (  ) 

The layout of a pointer.

cu_offset_t cuoo_layout_size ( cuoo_layout_t  layout  ) 

The number of bytes needed to represent layout rounded up to a multiple of its alignment.

cuoo_layout_t cuoo_layout_union ( cuoo_layout_t  lyo0,
cuoo_layout_t  lyo1 

Return a layout which can hold the union of lyo0 and lyo1. Holes present in both arguments are preserved.

cuoo_layout_t cuoo_layout_void (  ) 

The empty layout, this may be represented by NULL.
