NAME
mlx5dv_get_data_direct_sysfs_path - Get the sysfs path of a data direct device
SYNOPSIS
#include <infiniband/mlx5dv.h>
int
mlx5dv_get_data_direct_sysfs_path(struct ibv_context
*context, char *buf,
size_t buf_len)
DESCRIPTION
Get the sysfs path of the data direct device that is associated with the given context .
This lets an application to discover whether/which data direct device is associated with the given context .
ARGUMENTS
context
RDMA device context to work on.
|
buf |
The buffer where to place the sysfs path of the associated data direct device. |
buf_len
The length of the buffer.
RETURN VALUE
Upon success 0 is returned or the value of errno on a failure.
ERRORS
The below specific error values should be considered.
|
ENODEV |
There is no associated data direct device for the given *context*.
|
ENOSPC |
The input buffer size is too small to hold the full sysfs path.
NOTES
Upon succees, the caller should add the /sys/ prefix to get the full sysfs path.
