Object type that identifies a File stream and contains the information needed to control it, including its position indicator and all its state indicators.
file objects are usually created by the file::open method.
This object encapsulates the FILE object from the standard C library.
The description above has been adapted from the FILE reference page on cplusplus.com.
Example:
file f;
// Open the file in 'read' mode. Use "w" for writing
string fileName = GetExternalStorageDirectory() + "file.txt";
if (f.open(fileName, "r") >= 0)
{
// Read the whole file into the string buffer
string str;
f.readString(f.getSize(), str);
f.close();
}
