channel_create - create a channel
#include <zircon/syscalls.h> zx_status_t zx_channel_create(uint32_t options, zx_handle_t* out0, zx_handle_t* out1);
zx_channel_create() creates a channel, a bi-directional datagram-style message transport capable of sending raw data bytes as well as handles from one side to the other.
Two handles are returned on success, providing access to both sides of the channel. Messages written to one handle may be read from the opposite.
The handles will have ZX_RIGHT_TRANSFER (allowing them to be sent to another process via channel write), ZX_RIGHT_WRITE (allowing messages to be written to them), and ZX_RIGHT_READ (allowing messages to be read from them).
zx_channel_create() returns ZX_OK on success. In the event of failure, a negative error value is returned.
ZX_ERR_INVALID_ARGS out0 or out1 is an invalid pointer or NULL or options is any value other than 0.
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.
