GObjectTypeValueTable

Description [src]

struct GTypeValueTable {
  void (* value_init) (
    GValue* value
  );
  void (* value_free) (
    GValue* value
  );
  void (* value_copy) (
    const GValue* src_value,
    GValue* dest_value
  );
  gpointer (* value_peek_pointer) (
    const GValue* value
  );
  const gchar* collect_format;
  gchar* (* collect_value) (
    GValue* value,
    guint n_collect_values,
    GTypeCValue* collect_values,
    guint collect_flags
  );
  const gchar* lcopy_format;
  gchar* (* lcopy_value) (
    const GValue* value,
    guint n_collect_values,
    GTypeCValue* collect_values,
    guint collect_flags
  );
}

The GTypeValueTable provides the functions required by the GValue implementation, to serve as a container for values of a type.

collect_format

A string format describing how to collect the contents of this value bit-by-bit. Each character in the format represents an argument to be collected, and the characters themselves indicate the type of the argument. Currently supported arguments are: - ‘i’ - Integers. passed as collect_values[].v_int. - ‘l’ - Longs. passed as collect_values[].v_long. - ‘d’ - Doubles. passed as collect_values[].v_double. - ‘p’ - Pointers. passed as collect_values[].v_pointer. It should be noted that for variable argument list construction, ANSI C promotes every type smaller than an integer to an int, and floats to doubles. So for collection of short int or char, ‘i’ needs to be used, and for collection of floats ‘d’.

collect_value No description available.
lcopy_format

Format description of the arguments to collect for lcopy_value, analogous to collect_format. Usually, lcopy_format string consists only of ‘p’s to provide lcopy_value() with pointers to storage locations.

lcopy_value No description available.

Functions

g_type_value_table_peek
