I need some help converting a header file to hhf. I don't know how to declare the function prototypes properly.



#ifndef ADIO1600_H

#define ADIO1600_H



extern "C" __declspec(dllimport) unsigned short InPort(unsigned long Port);

extern "C" __declspec(dllimport) unsigned short InPortB(unsigned long Port);

extern "C" __declspec(dllimport) unsigned short OutPort(unsigned long Port, unsigned short Value);

extern "C" __declspec(dllimport) unsigned short OutPortB(unsigned long Port, unsigned char Value);



struct TPCI_COMMON_CONFIG

{

    unsigned short VendorID;

    unsigned short DeviceID;

    unsigned short Command;

    unsigned short Status;

    unsigned char RevisionID;

    unsigned char ProgIf;

    unsigned char SubClass;

    unsigned char BaseClass;

    unsigned char CacheLineSize;

    unsigned char LatencyTimer;

    unsigned char HeaderType;

    unsigned char BIST;

    unsigned long BaseAddresses[6];

    unsigned long Reserved1[2];

    unsigned long RomBaseAddress;

    unsigned long Reserved2[2];

    unsigned char InterruptLine;

    unsigned char InterruptPin;

    unsigned char MinimumGrant;

    unsigned char MaximumLatency;

};



#endif

Thanks

You can try this :). I can't guarantee that you'll have no problems but at least its a start. You may also need to change the external names for the functions depending on which C compiler the dll was coded with also.

 

#if( ! @defined( ADIO1600_H ))

?ADIO1600_H := true;



static 



    procedure InPort  

    (

    Port : uns32 

    );

	@cdecl; 

	returns( "ax" ); 

	external( "_InPort@4" ); 



    procedure InPortB

    (

    Port:uns32 

    );	 	 

	@cdecl; 

	returns( "ax" ); 

	external( "_InPortB@4" ); 



    procedure OutPort

    (

	Port : uns32;  

 	Value : uns16 

    );	

	

	@cdecl; 

	returns( "ax" ); 

	external( "_OutPort@6" );



    procedure OutPortB

    (

	Port : uns32;  

	Value : char

    );

	@cdecl; 

	returns( "ax" ); 

	external( "_OutPortB@5" );



type TCPI_COMMON_CONFIG : record 

    VendorID : uns16; 

    DeviceID : uns16; 

    Command  : uns16; 

    Status   : uns16; 

    RevisionID : uns8; 

    ProgIf   : uns8;  

    SubClass : uns8; 

    BaseClass : uns8; 

    CacheLineSize : uns8; 

    LatencyTimer : uns8; 

    HeaderType : uns8; 

    BIST : uns8; 

    BaseAddresses : uns32[6]; 

    Reserved1 : uns32[2]; 

    RomBaseAddress : uns32; 

    Reserved2 : uns32[2]; 

    InterruptLine : uns8; 

    InterruptPin : uns8; 

    MinimumGrant : uns8; 

    MaximumLatency : uns8; 

endrecord; 



#endif

Help converting header file

If you haven't done so yet, take a look at Chapter Three of "Windows Programming in Assembly Language" entitled "The C-Assembly Connection".
http://webster.cs.ucr.edu/Page_win32/WindowsAsmPgm/html/Ch03.html
This chapter contains a fair discussion of how to convert C constructs to HLA, specifically for the purpose of converting ".h" files to ".hhf" format.

Thanks for the help guys. I don't have the board in my pc at home, but hopefully I can try it out on Monday.

Cheers.
