class CreateBufferCollectionTokenGroup
Defined at line 1119 of file fidling/gen/sdk/fidl/fuchsia.sysmem/fuchsia.sysmem/cpp/fidl/fuchsia.sysmem/cpp/markers.h
Most sysmem clients and many participants don't need to care about this
message or about BufferCollectionTokenGroup(s) in general.
A BufferCollectionTokenGroup is used to create a 1 of N OR among N child
tokens. The child tokens which are not selected during aggregation will
fail (close), which a potential participant should notice when their
BufferCollection channel client endpoint sees PEER_CLOSED, allowing the
participant to clean up the speculative usage that didn't end up
happening (similarly to a normal BufferCollection server end closing
on failure of a logical buffer collection).
See comments on protocol BufferCollectionTokenGroup.
Any rights_attenuation_mask or AttachToken()/SetDispensable() to be
applied to the whole group can be achieved with a token for this purpose
as a direct parent of the group.
group_request - the server end of a BufferCollectionTokenGroup channel
to be served by sysmem.
