Description
GByteArray is based on GArray, to provide arrays of bytes which grow
automatically as elements are added.
To create a new GByteArray use g_byte_array_new().
To add elements to a GByteArray, use g_byte_array_append(), and
g_byte_array_prepend().
To set the size of a GByteArray, use g_byte_array_set_size().
To free a GByteArray, use g_byte_array_free().
Example 1. Using a GByteArray.
|   GByteArray *gbarray;
  gint i;
  gbarray = g_byte_array_new ();
  for (i = 0; i < 10000; i++)
    g_byte_array_append (gbarray, (guint8*) "abcd", 4);
  for (i = 0; i < 10000; i++)
    {
      g_assert (gbarray->data[4*i] == 'a');
      g_assert (gbarray->data[4*i+1] == 'b');
      g_assert (gbarray->data[4*i+2] == 'c');
      g_assert (gbarray->data[4*i+3] == 'd');
    }
  g_byte_array_free (gbarray, TRUE); |

The GByteArray struct allows access to the public fields of a GByteArray.
g_byte_array_sized_new ()
Creates a new GByteArray with reserved_size bytes preallocated. This
avoids frequent reallocation, if you are going to add many bytes to
the array. Note however that the size of the array is still 0.
g_byte_array_append ()
Adds the given bytes to the end of the GByteArray.
The array will grow in size automatically if necessary.
g_byte_array_prepend ()
Adds the given data to the start of the GByteArray.
The array will grow in size automatically if necessary.
g_byte_array_remove_index ()
Removes the byte at the given index from a GByteArray.
The following bytes are moved down one place.
g_byte_array_remove_index_fast ()
Removes the byte at the given index from a GByteArray.
The last element in the array is used to fill in the space, so this function
does not preserve the order of the GByteArray. But it is faster than
g_byte_array_remove_index().
g_byte_array_sort ()
Sorts a byte array, using compare_func which should be a qsort()-style
comparison function (returns -1 for first arg is less than second arg, 0 for
equal, 1 if first arg is greater than second arg).
g_byte_array_sort_with_data ()
Like g_byte_array_sort(), but the comparison function takes a user data argument.
g_byte_array_set_size ()
Sets the size of the GByteArray, expanding it if necessary.
g_byte_array_free ()
Frees the memory allocated by the GByteArray.
If free_segment is TRUE it frees the actual byte data.
