The files:
libdwarf.h
libdwarfp.h
dwarf.h
and most of the .h and .c files in this implementation of
libdwarf and libdwarfp are copyrighted according to the file
LIBDWARFCOPYRIGHT (which mentions the LGPL version 2.1).
Each file mentions the LGPL.
The full text of the LGPL 2.1 is provided in LGPL.txt
Another copyright used here in some files is the
two-clause BSD license, (FreeBSD license).
The libdwarf documentation:
libdwarf.mm
is based on material submitted to the UI PLSIG as proposed
interfaces for dwarf, but completely rewritten.
Copyright ownership is therefore SGI (but see the
document for details) and it seems clear that the
intent was there was to be free
copying with no fees.
libdwarfp.mm
is documentation of a set of interfaces
(not part of the UI PLSIG proposals)
and the document was written from scratch at SGI.
Copyright ownership is therefore SGI (but see the
document for details) and it seems clear that
