26 The \fBnvlist_lookup_nvpair()\fR function returns the nvpair with the matching
27 name, regardless of type. It is valid only for lists allocated with
28 \fBNV_UNIQUE_NAME\fR. See \fBnvlist_alloc\fR(9F).
31 The \fBnvlist_exists()\fR function returns success if any nvpair exists with
32 the given name. It is valid for all types of lists.
36 The \fBnvlist_lookup_nvpair()\fR function returns 0 on success and an error
40 The \fBnvlist_exists()\fR function returns \fBB_TRUE\fR if an nvpair with the
41 given name exists and \fBB_FALSE\fR otherwise.
45 The \fBnvlist_lookup_nvpair()\fR function will fail if:
52 There is an invalid argument.
61 No matching name-value pair is found.
70 The list was not allocated with \fBNV_UNIQUE_NAME\fR.
