I have a program where i want to print out the size of the terminal window in columns and rows.

To do this i want to call this function from int main()

int getConsoleSize(){
    CONSOLE_SCREEN_BUFFER_INFO csbi;
    int columns, rows;

    GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi);
    columns = csbi.srWindow.Right - csbi.srWindow.Left + 1;
    rows = csbi.srWindow.Bottom - csbi.srWindow.Top + 1;

    return columns, rows;
}

int main looks like this

int main(){
    int columns, rows = getConsoleSize();
    printf("columns: %dn", columns);
    printf("rows: %dn", rows);

    //prevent window from closing
    getc(stdin);

    return 0;
}

When calling the function getConsoleSize() it gives me the output columns: 5990652n rows: 30 which is clearly not correct. The columns output is also not consistent but is always at least 6-7 numbers long.
But when the code is copy pasted from the function directly into main() it seems to return the correct values with the outputs columns: 120n rows: 30.

Why is this and how do i fix it so that the function return the correct values
