With this example I got the following output after the path for the file:
Char view buffer:
position = 0 Limit = 512 capacity = 512
View buffer after loading:
position = 41 Limit = 512 capacity = 512
View buffer after flip:
position = 0 Limit = 41 length = 41
Byte buffer after limit update:
position = 0 Limit = 82 length = 82
Buffer contents written to file.
View buffer after loading:
position = 58 Limit = 512 capacity = 512
View buffer after flip:
position = 0 Limit = 58 length = 58
Byte buffer after limit update:
position = 0 Limit = 116 length = 116
Buffer contents written to file.
View buffer after loading:
position = 66 Limit = 512 capacity = 512
View buffer after flip:
position = 0 Limit = 66 length = 66
