BUG: H2INC 1.0 Does Not Support _syscall or _stdcall

ID: Q73368

The information in this article applies to:

Microsoft Macro Assembler for MS-DOS and OS/2, versions 6.0, 6.0a, 6.0b

SYMPTOMS

The Microsoft C to MASM Include file Translator (H2INC) version 1.0 that ships with the Microsoft Macro Assembler (MASM) version 6.0 does not support function prototypes using _syscall or _stdcall. The H2INC version 1.0 that ships with MASM version 6.0b supports _stdcall, but not _syscall.

RESOLUTION

Page 448 of the "Microsoft Macro Assembler Programmer's Guide" states that _syscall and _stdcall are accepted, but H2INC generates errors when it encounters prototypes containing these keywords. The _cdecl, _fortran, and _pascal language types are supported as documented.

STATUS

Microsoft has confirmed this to be a problem in H2INC version 1.0. We are researching this problem and will post new information here as it becomes available.

MORE INFORMATION

The following sample prototype demonstrates this problem:


   void _syscall sysfunc(void);

When this prototype is processed by H2INC, the following errors are generated:

warning HI4820: ignoring function definition : _syscall()
error HI2061: syntax error : identifier 'sysfunc'

-or-

error HI2143: syntax error: missing ';' before 'stdcall'
