Hello everyone. I was wondering if there was anyway to put some
assembally into C source code so that the assembally would be evaluated
exactly as it was written. I'm looking for some sort of standard
function or feature here so I am relitively sure that I am on topic (I
know some people that read this news group can be slightly brutal about
off topic posts). Anyways I'm just looking for a way to put a bit of
assembally into my code to take care of things that I would not be able
to otherwise. Thanks in advanced for any answers.

There's no portable way, so it would be off-topic. You'll need to find
a group dedicated to your hardware/compiler combination.

The question is on-topic, but the answer is no. There is no standard
way of embedding assembly language in C source. Your implementation
may provide extensions to do it, but you'd have to ask in a forum
which discusses that particular implementation.

The only "standard" way is to put it in an external routine. Actually I am
not even sire this is standard, but it has to be external.
Given you had some hex machine code could you put that in a string, (or
other array, say ints if you needed word alignment), cast the address of a
string to the address of a function and call the function?

Most C compilers provide some kind of extension that allows you to
write inline assembly code. Your proposed method uses only standard C
features, but it uses them in an *entirely* non-portable manner.
Using a compiler extension is no less portable, and is *far* more
likely to work and to be maintainable.

We must do something. This is something. Therefore, we must do this.
Yes, you can do it in C programming for microcontroller . Assembly code
can be inserted at any portion of the C code. You can try it in
microcontroller programming. Here is the link for some help: www.electronics.netmyne.com

Not standard C it can't, and the way the extensions work vary from
implementation to implementation.

Well, going through the tutorial I found, "In any real program, you will
use the gets or fgets functions instead to read text a line at a time."
on page http://www.electronics.netmyne.com/cprogramming7.html
Any tutorial that suggests using gets in real programs should be treated
with a degree of caution.
Going further I see:
int Main()
{
void Display(); // we called function Display
}
C is case sensitive, so using Main rather than main is not going to help
(if the linker is case insensitive, which it is allowed to be, it could
work by luck). Having a function named Main as well as one named main
would be legal, but I would consider it to be very bad practice.
There are other stupid errors as well. So having got further through it,
I would strongly recommend *against* that site.

Thants not all...oh no thats not all. This is some of the worst
programming style and structure I have ever seen. Anyplace that writes
source like this: (note: not actually copied)
#include <stdio.h>
main(){
char chr;
printf("hello\n ");
for(;;){
scanf("%c", &chr); /* in "real" programs we don't use this */
if(chr==a)
break;
}
}
CANNOT BE TRUSTED!!!

Actually, that would not be 'legal' unless one or both of them are
static. A program containing multiple external identifiers that are the
same (case-insensitive) in the first six characters is not strictly
conforming. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
