◆ createConnectedUnix()

Expected< std::unique_ptr< raw_socket_stream > > raw_socket_stream::createConnectedUnix ( StringRef SocketPath )

static

Create a raw_socket_stream connected to the UNIX domain socket at SocketPath.

Definition at line 320 of file raw_socket_stream.cpp.

References _, getSocketFD(), and llvm::Expected< T >::takeError().

◆ read()

ssize_t raw_socket_stream::read	(	char *	Ptr,
		size_t	Size,
		const std::chrono::milliseconds &	Timeout = `std::chrono::milliseconds(-1)`
	)

Attempt to read from the raw_socket_stream's file descriptor.

This method can optionally either block until data is read or an error has occurred or timeout after a specified amount of time has passed. By default the method will block until the socket has read data or encountered an error. If the read times out this method will return std::errc:timed_out

Parameters

Ptr	The start of the buffer that will hold any read data
Size	The number of bytes to be read
Timeout	An optional timeout duration in milliseconds

Definition at line 330 of file raw_socket_stream.cpp.

References llvm::raw_fd_ostream::error_detected(), llvm::raw_fd_ostream::get_fd(), manageTimeout(), Ptr, llvm::raw_fd_stream::read(), and Size.
