Thread: 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.
