GckAttributesref_sink

GckAttributes uses a floating reference count system. gck_builder_end() and gck_attributes_new_empty() both return floating references.

Calling this function on a GckAttributes with a floating reference will convert the floating reference into a full reference. Calling this function on a non-floating GckAttributes results in an additional normal reference being added.

In other words, if the attrs is floating, then this call “assumes ownership” of the floating reference, converting it to a normal reference. If the attrs is not floating, then this call adds a new normal reference increasing the reference count by one.

All Gck library functions that assume ownership of floating references are documented as such. Essentially any Gck function that performs an operation using a GckAttributes argument rather than operating on the attributes themselves, will accept a floating reference.
