mlx5dv_devx_destroy_event_channel - Destroy a DEVX event channel.
SYNOPSIS
#include <infiniband/mlx5dv.h>
struct mlx5dv_devx_event_channel {
int fd;
};
struct mlx5dv_devx_event_channel *
mlx5dv_devx_create_event_channel(struct ibv_context *context,
enum mlx5dv_devx_create_event_channel_flags flags)
void mlx5dv_devx_destroy_event_channel(struct mlx5dv_devx_event_channel *event_channel)
DESCRIPTION
Create or destroy a channel to be used for DEVX asynchronous events.
The create verb exposes an mlx5dv_devx_event_channel object that can be
used to read asynchronous DEVX events. This lets an application to
subscribe to get device events and once an event occurred read it from
this object.
ARGUMENTS
context
RDMA device context to create the channel on.
flags MLX5DV_DEVX_CREATE_EVENT_CHANNEL_FLAGS_OMIT_EV_DATA: omit the
event data on this channel.
RETURN VALUE
Upon success mlx5dv_devx_create_event_channel will return a new struct
mlx5dv_devx_event_channel object, on error NULL will be returned and
errno will be set.
