.SH NAME
|
|
nvme_get_nsid \- Retrieve the NSID from a namespace file descriptor
|
|
.SH SYNOPSIS
|
|
.B "int" nvme_get_nsid
|
|
.BI "(int fd " ","
|
|
.BI "__u32 *nsid " ");"
|
|
.SH ARGUMENTS
|
|
.IP "fd" 12
|
|
File descriptor of nvme namespace
|
|
.IP "nsid" 12
|
|
User pointer to namespace id
|
|
.SH "DESCRIPTION"
|
|
This should only be sent to namespace handles, not to controllers. The
|
|
kernel's interface returns the nsid as the return value. This is unfortunate
|
|
for many architectures that are incapable of allowing distinguishing a
|
|
namespace id > 0x80000000 from a negative error number.
|
|
.SH "RETURN"
|
|
0 if \fInsid\fP was set successfully or -1 with errno set otherwise.
