[OT] asm in bcc

[Stacy D. Coil]

Please excuse the slight off topic question.  I am trying to use bcc for a
couple of small routines.  There needs to be some assembly in it, and I
need to pass arguments back and forth.  I tried the following:

#define BDOOR_MAGIC  0x564D5868
#define BDOOR_CMD_GETVERSION           10
#define BDOOR_PORT   0x5658

typedef unsigned short uint16;
typedef unsigned uint32;




void
getVersion(version, magic)
uint32 *version; uint32 *magic;
{  
   uint32 v;
   uint32 m;
   

#asm
         push eax
         push ebx
         push ecx
         push edx
         
         mov eax, BDOOR_MAGIC
         mov ecx, BDOOR_CMD_GETVERSION
         mov dx, BDOOR_PORT
         in eax, dx
         mov v, eax
         mov m, ebx
         
         pop edx
         pop ecx
         pop ebx
         pop eax
#endasm
  
   *version = v;
   *magic = m;
   
}

But this returns and no symbol for v and m.  Could someone be kind enough
to show me how to pass varibles from c to assembly and back?

TIA,
