The macros in this section provide the varargs
parsing support needed in variadic GObject functions such as g_object_new() or g_object_set(). They currently support the
collection of integral types, floating point types and pointers.
union GTypeCValue
{
gint v_int;
glong v_long;
gint64 v_int64;
gdouble v_double;
gpointer v_pointer;
};
A union holding one collected value.
#define G_VALUE_COLLECT(value, var_args, flags, __error)
Collects a variable argument value from a va_list. We have to implement the varargs collection as a macro, because on some systems va_list variables cannot be passed by reference.
value : |
a GValue return location.
value
is supposed to be initialized according to the value type to be
collected
|
var_args : |
the va_list variable; it may be evaluated multiple times |
flags : |
flags which are passed on to the
collect_value()
function of the GTypeValueTable of value.
|
__error : |
a gchar** variable that will be modified to hold a g_new() allocated error messages if something fails
|
#define G_VALUE_LCOPY(value, var_args, flags, __error)
Collects a value's variable argument locations from a va_list.
value : |
a GValue return location.
value
is supposed to be initialized according to the value type to be
collected
|
var_args : |
the va_list variable; it may be evaluated multiple times |
flags : |
flags which are passed on to the lcopy_value()
function of the GTypeValueTable of value.
|
__error : |
a gchar** variable that will be modified to hold a g_new() allocated error messages if something fails
|
#define G_VALUE_COLLECT_FORMAT_MAX_LENGTH (8)
The maximal number of GTypeCValues which can be collected for a single GValue.
