Greetings all !
I have a piece of sample code from an open library. It was supposedly written for msvs, but I am using codeblocks with mingw compiler on a windows 7 machine.
The (so I think) relevant piece of code is:
The error I get is :
error: 'errno_t' was not declared in this scope|
I searched online for what to do with errno_t, but all I figured out is about its purpose. What can I do to fix this and make the program work ? Thank you.
Kind regards, T

I don't think
errno_t
exists. Instead, you should try
decltype
(errno)
By using the
typedef
keyword, you make
err
a type instead of a variable.
However, in this case since you immediately assign to the variable, you can forget about the data type and let the compiler figure it out for you:
auto
err = fopen(&infile, infilename,
"r"
);
Though, really, if you are going to use C++ at all, you should use it completely and ignore C:
1 2 3 4 5 6 7 8
if(std::ifstream infile {infilename})
//success
//error
There's generally no use for detailed error information except in specialized cases. For the most part, your only concern is whether you could open the file or not.
