read/write binary or classic text files mainly, there are several methods. i don't recall all but can check c++ reference, filestream for ex
found back in kinda preset manager that stored datas as text lines i used something like this for ex:
void Preset::SaveToFile(string Path)
{
ofstream outfile;
outfile.open(Path);
// do your lines stuff here ie float to string
outfile << "blablastring" << endl; //line0
outfile << "second line txt" << endl; //line 1 ect, or use a loop
outfile.close();
}
///////////////////////////////
void Preset::ReadFromFile(string Path)
{
fstream infile;
infile.open(Path);
string line;
float F_value = 0;
while (getline(infile, line))
{
getline(infile, line);
F_value = atof(line.c_str()); //string to F value line after line
}
infile.close();
}
//////////////////////////////////////////
or used a different binary one on in other project, among those lines to read wav floats that where saved in a raw binary file, so easier as had no header to mess with
but maybe could start the 'effective' reading after the number of bytes of header if plan using wave files
myfile = fopen(input_file_name, "rb"); //read binary mode
fseek(myfile, 0L, SEEK_END); //scrub all the file
nb_elements = ftell(myfile); // retrieve nb of elements
nb_elements /= 4; // as floats are 4 bytes
rewind(myfile); //returns back at start
values = new float[nb_elements]; // array of float that will get values
fread(values, sizeof(float), nb_elements, myfile); // read file bytes and store to values array
fclose(myfile);
// do stuff with the retrieved array then
