-- This package (and children) provide interface definitions to the standard
|
|
-- OS/2 Library. They are merely a translation of the various <bse*.h> files.
|
|
|
|
-- It is intended that higher level interfaces (with better names, and
|
|
-- stronger typing!) be built on top of this one for Ada (i.e. clean)
|
|
-- programming.
|
|
|
|
-- We have chosen to keep names, types, etc. as close as possible to the
|
|
-- C definition to provide easier reference to the documentation. The main
|
|
-- exception is when a formal and its type (in C) differed only by the case
|
|
-- of letters (like in HMUX hmux). In this case, we have prepended "F_" to
|
|
-- the formal (i.e. F_hmux : HMUX).
