passing structures to functions

I am currently having trouble passing structures to functions.
Here is a portion of my code where Select_File is the function and
I am trying to pass the struct TXT to the function for editing.

Code:

---

typedef struct
{
int position
int chars
int newlines
}TXT;

void Select_File(TXT *file_info );

int main(void)
{

TXT *file_info;

Select_File( file_info );
}

void Select_File( TXT *file_info )
{


}

---

I am sure whatever I am doing wrong is clear to someone else, so if anyone is willing to offer help I would be much appreciative.

Don't forget your semicolons:

Code:

---

typedef struct
{
int position;
int chars;
int newlines;
}TXT;

---

Code:

---

int main(void)
{

TXT *file_info;

Select_File( file_info );
}

---

Minor warning: You seem to be actually passing pointers to structures. Be warned that file_info isn't pointing to any valid TXT object yet.

so I should just replace file_info with TXT where the function call begins

like this?

Select_File( TXT )

>so I should just replace file_info with TXT where the function call begins
Dante's point is that file_info, while being a valid TXT pointer, doesn't actually point to any memory that you can use yet. If you're going to use it only in that function and then discard it you're fine. If you're going to point it to something and expect to use it after the function returns then you'll need to do a little more work. One easy solution is to just grab some memory in main and let Select_File fill it with useful stuff:

Code:

---

int main()
{
  TXT *file_info = new TXT;

  Select_File(file_info);
  // Use file_info

  delete file_info;
}

---

Or create an object of typ TXT and pass the address of that object:

Code:

---

int main()
{
  TXT file_info;

  Select_File(&file_info);
}

---

Or use a pointer and point it to an object of type TXT and pass the pointer, that way you still have file_info as a pointer in main and you don't have to worry about memory management.

Thank you all for all of your help. Especially Sandra;)
