class UnixSocketRaw

Defined at line 130 of file ../../third_party/perfetto/include/perfetto/ext/base/unix_socket.h

UnixSocketRaw is a basic wrapper around sockets. It exposes wrapper

methods that take care of most common pitfalls (e.g., marking fd as

O_CLOEXEC, avoiding SIGPIPE, properly handling partial writes). It is used as

a building block for the more sophisticated UnixSocket class which depends

on base::TaskRunner.

Public Methods

UnixSocketRaw CreateMayFail (SockFamily family, SockType type)

Creates a new unconnected unix socket.

std::pair<UnixSocketRaw, UnixSocketRaw> CreatePairPosix (SockFamily , SockType )

Crates a pair of connected sockets.

void UnixSocketRaw ()

Creates an uninitialized unix socket.

void UnixSocketRaw (ScopedSocketHandle , SockFamily , SockType )

Creates a unix socket adopting an existing file descriptor. This is

typically used to inherit fds from init via environment variables.

bool Bind (const std::string & socket_name)

bool Listen ()

bool Connect (const std::string & socket_name)

bool SetTxTimeout (uint32_t timeout_ms)

bool SetRxTimeout (uint32_t timeout_ms)

void Shutdown ()

void SetBlocking (bool )

void DcheckIsBlocking (bool expected)

void SetRetainOnExec (bool retain)

PlatformHandle watch_handle ()

This is the handle that passed to TaskRunner.AddFileDescriptorWatch().

On UNIX this is just the socket FD. On Windows, we need to create a

dedicated event object.

ScopedSocketHandle ReleaseFd ()

Defined at line 178 of file ../../third_party/perfetto/include/perfetto/ext/base/unix_socket.h

ssize_t Send (const void * msg, size_t len, const int * send_fds, size_t num_fds)

|send_fds| and |num_fds| are ignored on Windows.

ssize_t Receive (void * msg, size_t len, ScopedFile * fd_vec, size_t max_files)

|fd_vec| and |max_files| are ignored on Windows.

ssize_t SendMsgAllPosix (struct msghdr * msg)

Re-enter sendmsg until all the data has been sent or an error occurs.

TODO(fmayer): Figure out how to do timeouts here for heapprofd.

ssize_t SendStr (const std::string & str)

Defined at line 186 of file ../../third_party/perfetto/include/perfetto/ext/base/unix_socket.h

void ShiftMsgHdrPosix (size_t n, struct msghdr * msg)

Exposed for testing only.

Update msghdr so subsequent sendmsg will send data that remains after n

bytes have already been sent.
