GObjectTypeValueTable

Description [src] 

struct GTypeValueTable {
  GTypeValueInitFunc value_init;
  GTypeValueFreeFunc value_free;
  GTypeValueCopyFunc value_copy;
  GTypeValuePeekPointerFunc value_peek_pointer;
  const gchar* collect_format;
  GTypeValueCollectFunc collect_value;
  const gchar* lcopy_format;
  GTypeValueLCopyFunc lcopy_value;
}
  • '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'. The GTypeValueTable provides the functions required by the GValue implementation, to serve as a container for values of a type.

Structure members
value_init

Function to initialize a GValue.

value_free

Function to free a GValue.

value_copy

Function to copy a GValue.

value_peek_pointer

Function to peek the contents of a GValue if they fit into a pointer.

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:.

collect_value

Function to initialize a GValue from the values collected from variadic arguments.

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

Function to store the contents of a value into the locations collected from variadic arguments.

Functions

g_type_value_table_peek

Returns the location of the GTypeValueTable associated with type.
