.SH "DESCRIPTION"
|
|
.sp
|
|
Retrieves NVMe Error log page from an NVMe device and provides the returned structure\&.
|
|
.sp
|
|
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
|
|
.sp
|
|
On success, the returned error log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse\&.

It is probably a bad idea to not redirect stdout when using this mode\&.
