source: libabac/abac.h @ d9c3886

mei_rt2mei_rt2_fix_1
Last change on this file since d9c3886 was d9c3886, checked in by Mei <mei@…>, 12 years ago

1) add 2 more query calls in abac.hh that take Role and Oset instead of

strings. Add supporting code in libabac that will take abac_aspect_t
and make query term directly instead of doing stringify the structure
and do string->yyparse->abac_aspect_t again.

2) start on inline doc into abac.hh
3) tweaked some scripts in examples directory
  • Property mode set to 100644
