-
--- 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).

-
- -- Coprocessor stack register element.

- hisig : ULONG; -- High 32-bits of the mantissa
- signexp : USHORT; -- Sign and exponent
- end record;

- procedure Must_Not_Fail (Return_Code : OS2Lib.APIRET);
- pragma Inline (Must_Not_Fail);
- -- Many OS/2 functions return APIRET and are not supposed to fail. In C
- -- style, these would be called as procedures, disregarding the returned
- -- value. This procedure can be used to achieve the same effect with a
- -- call of the form: Must_Not_Fail (Some_OS2_Function (...));
-
- procedure Sem_Must_Not_Fail (Return_Code : OS2Lib.APIRET);
- pragma Inline (Sem_Must_Not_Fail);
- -- Similar to Must_Not_Fail, but used in the case of DosPostEventSem,
- -- where the "error" code ERROR_ALREADY_POSTED is not really an error.
