Q46129: Problem with QuickC Inline Assembler INT Call and Typedefs

Article: Q46129
Version(s): 2.00
Operating System: MS-DOS
Flags: ENDUSER | S_QuickASM buglist2.00
Last Modified: 27-JUN-1989

When compiled with QuickC Version 2.00, the code below compiles and
gives the following message for the line containing the initialization
of bar:

   error C2064 : term does not evaluate to function

Removing the parentheses from the 0 in the initialization causes the
following message:

   error C2143 : missing ')' before 'constant'

Inline assembler code must contain an interrupt call (INT) for this
error to occur. Using a simple type cast before the typedef'ed type
cast solves the problem. In the following example, reverse the order
of the initializations for bar and fad to put the simple typecast
first.

Code Example
------------

typedef unsigned short far *FOO;

FOO   bar;
float fad;

    void main( void )
    {
        _asm { int 11h }

        bar = ((FOO) (0));   /* reversing this line with the next */
        fad = (float)3.4;    /* prevents the problem              */
    }

Microsoft has confirmed this to be a problem in QuickC Version 2.00.
We are researching this problem and will post new information as it
becomes available.
