.SH DESCRIPTION
.PP
The
.BR io_uring_prep_setxattr (3)
function prepares a request to set an extended attribute value. The submission 
queue entry 
.I sqe
is setup to set the
.I value
of the extended attribute identified by
.I name
and associated with the given
.I path
in the filesystem with modifier flags
.IR flags .
The
.I len
argument specifies the size (in bytes) of
.IR value .

.BR io_uring_prep_fsetxattr (3)
is identical to 
.BR io_uring_prep_setxattr (3),
only the extended attribute is set on the open file referred to by
.I fd
in place of
.IR path .

This function prepares an async 
.BR setxattr (2)
request. See that man page for details.

.SH RETURN VALUE
None
