Declaration [src]
gconstpointer
g_variant_get_data (
GVariant* value
)
Description [src]
Returns a pointer to the serialized form of a GVariant instance.
The returned data may not be in fully-normalised form if read from an
untrusted source. The returned data must not be freed; it remains
valid for as long as value exists.
If value is a fixed-sized value that was deserialized from a
corrupted serialized container then NULL may be returned. In this
case, the proper thing to do is typically to use the appropriate
number of nul bytes in place of value. If value is not fixed-sized
then NULL is never returned.
In the case that value is already in serialized form, this function
is O(1). If the value is not already in serialized form,
serialization occurs implicitly and is approximately O(n) in the size
of the result.
To deserialize the data returned by this function, in addition to the
serialized data, you must know the type of the GVariant, and (if the
machine might be different) the endianness of the machine that stored
it. As a result, file formats or network messages that incorporate
serialized GVariants must include this information either
implicitly (for instance “the file always contains a
G_VARIANT_TYPE_VARIANT and it is always in little-endian order”) or
explicitly (by storing the type and/or endianness in addition to the
serialized data).
