zx_socket_create

NAME

Create a socket.

SYNOPSIS

#include <zircon/syscalls.h>

zx_status_t zx_socket_create(uint32_t options,
                             zx_handle_t* out0,
                             zx_handle_t* out1);

DESCRIPTION

zx_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 ZX_SOCKET_STREAM or ZX_SOCKET_DATAGRAM flag.

RIGHTS

TODO(fxbug.dev/32253)

RETURN VALUE

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

ERRORS

ZX_ERR_INVALID_ARGS out0 or out1 is an invalid pointer or NULL or options is any value other than ZX_SOCKET_STREAM or ZX_SOCKET_DATAGRAM.

ZX_ERR_NO_MEMORY Failure due to lack of memory. There is no good way for userspace to handle this (unlikely) error. In a future build this error will no longer occur.

LIMITATIONS

The maximum capacity is not currently set-able.
