Passing an array of structs

SleepingUdon08 · 04-03-2009, 10:43 PM

Hi I'm new to this forum. Sorry if how I present my problem is not the correct way.

What I'm trying to do is pass an array of structures to a function. Here is glimpse of the relevant parts of my code.

Code:

...
void manual_replace ( struct key *key_list, char *txt_p, int size); <-- prototype
...

int main (void) 
{
       ...
       struct key{
	    char encoded;
	    char decoded;
        };
	
        struct key key_list[26];
       ...
       manual_replace(key_list, text, text_size); <-- calling the function
       ...
       return 0;
}

void manual_replace ( struct key *key_list, char *txt_p, int size)

{
	printf("%c", key_list[1].encoded);
	printf ("%c %d", txt_p[0], size);
	getchar();

	return;
}

The other arguments work just fine. It's only when I call a part of a struct that I get an error. BTW I can't do anything that is C99 only (class rules ).

What error are you getting?

If it's telling you that struct key is undefined you need to move

Code:

struct key{
  char encoded;
  char decoded;
};

outside of main
