SYNOPSIS
bfd_boolean bfd_check_compression_header
(bfd *abfd, bfd_byte *contents, asection *sec,
- bfd_size_type *uncompressed_size);
+ bfd_size_type *uncompressed_size,
+ unsigned int *uncompressed_alignment_power);
DESCRIPTION
Check the compression header at CONTENTS of SEC in ABFD and
- store the uncompressed size in UNCOMPRESSED_SIZE if the
- compression header is valid.
+ store the uncompressed size in UNCOMPRESSED_SIZE and the
+ uncompressed data alignment in UNCOMPRESSED_ALIGNMENT_POWER
+ if the compression header is valid.
RETURNS
Return TRUE if the compression header is valid.
