Passing QFile to function

Question

I get an illegal indirection error at generateCSVHeader(*file4);.

function declaration:

void generateCSVHeader(QFile * file);

function use:

str="MyData.csv";
QFile file4(str);
generateCSVHeader(*file4);

when I drop the dereference designator, it gives me a cannot convert QFIle to QFile * error.

Answer 1

You should pass pointer to your QFile object (which is an address) instead of passing the object itself (dereferencing is irrelevant, because it is used only with pointers, not objects). To get an address of your object, you should use the & operator. So you have to invoke your function like this:

generateCSVHeader(&file4)

Also, you may consider using references instead of pointers.
