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;

'i': Integers, passed ascollect_values[].v_int'l': Longs, passed ascollect_values[].v_long'd': Doubles, passed ascollect_values[].v_double'p': Pointers, passed ascollect_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:GTypeValueInitFuncFunction to initialize a GValue.
value_free:GTypeValueFreeFuncFunction to free a GValue.
value_copy:GTypeValueCopyFuncFunction to copy a GValue.
value_peek_pointer:GTypeValuePeekPointerFuncFunction to peek the contents of a GValue if they fit into a pointer.
collect_format:const gchar*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:GTypeValueCollectFuncFunction to initialize a GValue from the values collected from variadic arguments.
lcopy_format:const gchar*Format description of the arguments to collect for
lcopy_value, analogous tocollect_format. Usually,lcopy_formatstring consists only of'p's to providelcopy_value()with pointers to storage locations.lcopy_value:GTypeValueLCopyFuncFunction to store the contents of a value into the locations collected from variadic arguments.
