.SH ARGUMENTS
|
|
.IP "fd" 12
|
|
File descriptor of nvme device
|
|
.IP "rgo" 12
|
|
Whether to retrieve ANA groups only (no NSIDs)
|
|
.IP "rae" 12
|
|
Whether to retain asynchronous events
|
|
.IP "retries" 12
|
|
The maximum number of times to retry on log page changes
|
|
.IP "log" 12
|
|
Pointer to a buffer to receive the ANA log page
|
|
.IP "len" 12
|
|
Input: the length of the log page buffer.
|
|
Output: the actual length of the ANA log page.
|
|
.SH "DESCRIPTION"
|
|
See \fIstruct nvme_ana_log\fP for the definition of the returned structure.
|
|
.SH "RETURN"
|
|
If successful, returns 0 and sets *len to the actual log page length.
|
|
If unsuccessful, returns the nvme command status if a response was received
|
|
(see \fIenum nvme_status_field\fP) or -1 with errno set otherwise.
|
|
Sets errno = EINVAL if retries == 0.
|
|
Sets errno = EAGAIN if unable to read the log page atomically
|
|
because chgcnt changed during each of the retries attempts.
|
|
Sets errno = ENOSPC if the full log page does not fit in the provided buffer.
