GByteArray

typedef struct {
  guint8 *data;
  guint	  len;
} GByteArray;

The GByteArray struct allows access to the public fields of a GByteArray.

g_byte_array_new ()

GByteArray*         g_byte_array_new                    (void);

Creates a new GByteArray with a reference count of 1.

g_byte_array_sized_new ()

GByteArray*         g_byte_array_sized_new              (guint reserved_size);

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_ref ()

GByteArray *        g_byte_array_ref                    (GByteArray *array);

Atomically increments the reference count of array by one. This function is MT-safe and may be called from any thread.

Since 2.22

g_byte_array_unref ()

void                g_byte_array_unref                  (GByteArray *array);

Atomically decrements the reference count of array by one. If the reference count drops to 0, all memory allocated by the array is released. This function is MT-safe and may be called from any thread.

Since 2.22

g_byte_array_append ()

GByteArray*         g_byte_array_append                 (GByteArray *array,
                                                         const guint8 *data,
                                                         guint len);

Adds the given bytes to the end of the GByteArray. The array will grow in size automatically if necessary.

g_byte_array_prepend ()

GByteArray*         g_byte_array_prepend                (GByteArray *array,
                                                         const guint8 *data,
                                                         guint len);

Adds the given data to the start of the GByteArray. The array will grow in size automatically if necessary.

g_byte_array_remove_index ()

GByteArray*         g_byte_array_remove_index           (GByteArray *array,
                                                         guint 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 ()

GByteArray*         g_byte_array_remove_index_fast      (GByteArray *array,
                                                         guint index_);

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_remove_range ()

GByteArray*         g_byte_array_remove_range           (GByteArray *array,
                                                         guint index_,
                                                         guint length);

Removes the given number of bytes starting at the given index from a GByteArray. The following elements are moved to close the gap.

Since 2.4

g_byte_array_sort ()

void                g_byte_array_sort                   (GByteArray *array,
                                                         GCompareFunc compare_func);

Sorts a byte array, using compare_func which should be a qsort()-style comparison function (returns less than zero for first arg is less than second arg, zero for equal, greater than zero if first arg is greater than second arg).

If two array elements compare equal, their order in the sorted array is undefined.

g_byte_array_sort_with_data ()

void                g_byte_array_sort_with_data         (GByteArray *array,
                                                         GCompareDataFunc compare_func,
                                                         gpointer user_data);

Like g_byte_array_sort(), but the comparison function takes an extra user data argument.

g_byte_array_set_size ()

GByteArray*         g_byte_array_set_size               (GByteArray *array,
                                                         guint length);

Sets the size of the GByteArray, expanding it if necessary.

g_byte_array_free ()

guint8*             g_byte_array_free                   (GByteArray *array,
                                                         gboolean free_segment);

Frees the memory allocated by the GByteArray. If free_segment is TRUE it frees the actual byte data. If the reference count of array is greater than one, the GByteArray wrapper is preserved but the size of array will be set to zero.
