Description:

public class FileInputStream : InputStream, Seekable

Example: FileIOStream:

public static int main (string[] args) {
try {
// Create a file that can only be accessed by the current user:
File file = File.new_for_path ("my-test.bin");
FileIOStream ios = file.create_readwrite (FileCreateFlags.PRIVATE);

//
// Write data:
//

size_t bytes_written;
FileOutputStream os = ios.output_stream as FileOutputStream;
os.write_all ("My 1. line\n".data, out bytes_written);
os.write_all ("My 2. line\n".data, out bytes_written);

DataOutputStream dos = new DataOutputStream (os);
dos.put_string ("My 3. line\n");
dos.put_int16 (10);


//
// Set the file pointer to the beginning of the stream:
//
assert (ios.can_seek ());
ios.seek (0, SeekType.SET);


//
// Read n bytes:
//

FileInputStream @is = ios.input_stream as FileInputStream;

// Output: ``M``
uint8 buffer[1];
size_t size = @is.read (buffer);
stdout.write (buffer, size);

// Output: ``y 1. line``
DataInputStream dis = new DataInputStream (@is);
string str = dis.read_line ();
print ("%s\n", str);

// Output: ``My 2. line``
str = dis.read_line ();
print ("%s\n", str);

// Output: ``My 3. line``
str = dis.read_line ();
print ("%s\n", str);

// Output: ``10``
int16 i = dis.read_int16 ();
print ("%d\n", i);
} catch (Error e) {
print ("Error: %s\n", e.message);
}

return 0;
