[Dev-C++] outportb

[Vakku J. C. <va...@ya...>]

hi,

I am new user dev ++ and also new to c

"outportb" the compiler says 

C:\WINDOWS\TEMP\ccBgszfb.o(.text+0x46):si.c: undefined
reference to `outportb'
C:\WINDOWS\TEMP\ccBgszfb.o(.text+0x5b):si.c: undefined
reference to `outportb'
C:\WINDOWS\TEMP\ccBgszfb.o(.text+0x6d):si.c: undefined
reference to `outportb'
C:\WINDOWS\TEMP\ccBgszfb.o(.text+0x7f):si.c: undefined
reference to `outportb'
C:\WINDOWS\TEMP\ccBgszfb.o(.text+0x91):si.c: undefined
reference to `outportb'
C:\WINDOWS\TEMP\ccBgszfb.o(.text+0xa3):si.c: more
undefined references to `outportb' follow
C:\WINDOWS\TEMP\ccBgszfb.o(.text+0xc9):si.c: undefined
reference to `inportb'
C:\WINDOWS\TEMP\ccBgszfb.o(.text+0xe8):si.c: undefined
reference to `inportb'
C:\WINDOWS\TEMP\ccBgszfb.o(.text+0x120):si.c:
undefined reference to `outportb'


Can some one help me to get this solved. 

Thanks
Vakku

outportb is not standard, and every compiler has his own function.

For Dev-C++, the functions are "_outp()" and "_inp()".

But remember, these functions can't be used under windows NT/2000/XP.

gUI

Hi all,

How do i get the names of the functions...

below is my small program..

can some one go through and help me to find out why
this is not working .

Thanks
Vakku



  #include<dos.h>
  #include<stdio.h>
  #include<conio.h>

  #define  port1  0x3f8

  void main(void)
  {
    int c;
    int ch;
    _outp(port1 + 1,0);
    _outp(port1 + 3, 0x80);
    _outp(port1 + 0, 0x0C);
    _outp(port1 + 1, 0x00);
    _outp(port1 + 3, 0x03);
    _outp(port1 + 2, 0x00);

    printf("\nSample Comm's Program. Press ESC to quit
\n");

    do { c = _inp(port1 + 5) ;
	    if ( c & 1 )
	    {
	      ch = _inp (port1);
	      printf ("%c",ch );
	    }

	    if (kbhit())
	    {
	      _outp(port1,ch);
	    }
       }
    while ( ch!=27 );


}

[Dev-C++] Socket Programming

[Vakku J. C. <va...@ya...>]

 hi all,
 
 I am new user dev ++ and also new to c

 Can some one help me in implementing a tcp/ip socket
using c. My ultimate goal is using minimum hardware
interface a microcontroller to the ethernet.

As mentioned above i am very new to this field, all i
know is microcontroller. As a kickstart for this , i
would like to do a communication with pc-pc on the
existing ethernet layer what we have in our office.
I need to mention that i have never done socket
programming before. Please suggest me all the possible
ways for reaching my goal (any books for a beginner
like me ).

I hope this wont be a big request for all the highly
experinced people in here ..

Thanks in advance

vakku.

I am going to take a slightly different approach than most, since you
mentioned wanting to attach a microcontroller to the ethernet.  If you
meant an x86 CPU running Windows (which is the only platform supported by
Dev-C++, as far as I know), then you should check out the books that have
already been mentioned in other posts.

If, instead, you are running on a tiny processor (8051, 6501, PIC, etc),
you might be interested in the following very lightweight and very small
TCP/IP stacks.  Both are by the same guy, one is a little bit more capable
than the other.

WARNING : To the best of my knowledge, neither stack uses the standard
"Berkeley Sockets" functional API, which is what both Windows and UNIX
networking is usually based on.  Learning to use either of these stacks
WILL NOT help you in learning to program networking applications for
Windows or UNIX.  But if all you want is a tiny computer talking on the
network, they might fit your requirements.  (It is possible that the lwIP
stack actually does support the "Berkeley Sockets" standard API, but they
claim it is an optional component, and I don't know how closely they
actually followed all of the specifications for that API.)
