Thread: Pointer problem with FILE *f in function

I declared

Code:

FILE *f = NULL;

in the main-function. Then I call a function, where I close the file f and open it again. I thought, the function prototype can look like this:

Code:

void my_function(FILE *f);

and I call it in the main-function this way:

Code:

my_function(f);

But now, in my_function, when I close the file and open it again, the pointer is messed up in the main-function.


When I have the prototype this way:

Code:

void my_function(FILE **f);

and call the function this way:

Code:

my_function(&f);

then it works, but it doesn't looks that good with the pointer to the pointer...

Any suggestions how to remove the double-pointer?

thx
