David Crawshaw 174b093c62 [kernel][socket] control plane

Implement an out-of-band socket control plane to be used for
configuring a socket connection. Typical POSIX functions (like
bind and listen) can be implemented by sending an out-of-band
message to the other side of the socket using MX_SOCKET_CONTROL.

mx_socket_create

NAME

socket_create - create a socket

SYNOPSIS

#include <magenta/syscalls.h>

mx_status_t mx_socket_create(uint32_t options,
                             mx_handle_t* out0, mx_handle_t* out1);

DESCRIPTION

socket_create() creates a socket, a connected pair of bidirectional stream transports, that can move only data, and that have a maximum capacity.

Data written to one handle may be read from the opposite.

The options must set either the MX_SOCKET_STREAM or MX_SOCKET_DATAGRAM flag. The MX_SOCKET_HAS_CONTROL flag can also be set to enable the socket control plane.

RETURN VALUE

socket_create() returns MX_OK on success. In the event of failure, one of the following values is returned.

ERRORS

MX_ERR_INVALID_ARGS out0 or out1 is an invalid pointer or NULL or options is any value other than 0.

MX_ERR_NO_MEMORY (Temporary) Failure due to lack of memory.

LIMITATIONS

The maximum capacity is not currently set-able or get-able.
