\usage{
H5Aopen(h5obj, name)

h5obj,
n,

}
\arguments{
\item{h5obj}{An object of class \linkS4class{H5IdComponent} representing a H5 object
identifier (file, group, or dataset). See \code{\link[=H5Fcreate]{H5Fcreate()}}, \code{\link[=H5Fopen]{H5Fopen()}},
\code{\link[=H5Gcreate]{H5Gcreate()}}, \code{\link[=H5Gopen]{H5Gopen()}}, \code{\link[=H5Dcreate]{H5Dcreate()}}, or \code{\link[=H5Dopen]{H5Dopen()}} to create an object of this kind.}
\item{name}{The name of the attribute (character).}
\item{objname}{The name of the object the attribute belongs to.}
\item{n}{Opens attribute number \code{n} in the given order and index. Indexing is C-style, base-0,
so the first attribute is opened with \code{n=0}.}
\item{index_type}{See \code{h5const("H5_INDEX")} for possible arguments.}
\item{order}{See \code{h5const("H5_ITER")} for possible arguments.}
