Constants

MAX_COMPLETIONS_PER_EVENT

Limit on the number of completions delivered in a single OnCompletion event to avoid exceeding the Zircon channel message size limit (ZX_CHANNEL_MAX_MSG_BYTES = 64KB) even with scatter-gather buffer chaining.

REQUEST_MAX

Limit on the number of Requests in one call to QueueRequests().

VMO_VECTOR_MAX

Limit on the number of VMOs in one call to RegisterVmos() or UnregisterVmos(). Bounded by the Zircon channel handle limit (ZX_CHANNEL_MAX_MSG_HANDLES = 64) since RegisterVmos() returns a vector of VMO handles.
