class SynchronousProxy
Defined at line 23 of file ../../sdk/lib/fidl/hlcpp/include/lib/fidl/cpp/internal/synchronous_proxy.h
Manages the client state for a synchronous interface.
A |SynchronousProxy| manages the client state for a sychronous interface.
This object validates messages before sending them to the remote endpoint,
and (optionally) blocks until it receives a reply.
Instances of this class are thread-safe.
Public Methods
void SynchronousProxy (zx::channel channel)Creates a |SynchronousProxy| that wraps the given channel.

void ~SynchronousProxy ()Defined at line 17 of file ../../sdk/lib/fidl/hlcpp/internal/synchronous_proxy.cc
zx::channel TakeChannel ()Returns the underlying channel from this object.
The |SynchronousProxy| does not attempt to synchronize this operation with
|Send| or |Call|.

zx_status_t Send (const fidl_type_t * type, HLCPPOutgoingMessage message)Validates that |message| matches the given |type| and sends the message
through the underlying channel.
Does not block.
Returns an error if validation or writing fails.

zx_status_t Call (const fidl_type_t * request_type, const fidl_type_t * response_type, HLCPPOutgoingMessage request, HLCPPIncomingMessage * response)Validate that |request| matches the given |request_type| and sends
|request| through the underlying channel. Blocks until it receives a
response, which is then decoded according to |response_type| and returned
in |response_type|.
Blocks until the remote endpoint replied.
Returns an error if validation, writing, reading, or decoding fails.
