how to put files and exported functions in one dll?-CodePudding

for some reason, I needed to put a file in a DLL. I knew I could put it in a pure resource DLL, but I didn't want anyone else to know how to read the file。 So I want to be able to put this file in a DLL along with the functions on how to read the file. Does anyone know how to do that ? Thanks

Here is one idea. Store the file as base64 encoded with

$ cat file.txt
Hello World
Hello World
Hello World
Hello World
Hello World
Hello World

$ cat file.txt | base64 > base64.txt

$ cat base64.txt
SGVsbG8gV29ybGQKSGVsbG8gV29ybGQKSGVsbG8gV29ybGQKSGVsbG8gV29ybGQKSGVsbG8gV29y
bGQKSGVsbG8gV29ybGQKCg==

Then in your c file

static std::string fileout = R"(
SGVsbG8gV29ybGQKSGVsbG8gV29ybGQKSGVsbG8gV29ybGQKSGVsbG8gV29ybGQKSGVsbG8gV29y
bGQKSGVsbG8gV29ybGQKCg==
)";

std::string readme() {
    return base64::decode( fileout );
}

You can find several base64::decode() versions here: Base64 decode snippet in C
