H5L: HDF5 Link Interface
In patperry/rhdf5: HDF5 interface to R

Description Usage Arguments Details Value Author(s) References See Also Examples

The Link interface, H5L, functions create and manipulate links in an HDF5 group. This interface includes functions that enable the creation and use of user-defined link classes.

1 2	H5Lexists (h5loc, name) H5Lget_info (h5loc, name)

`h5loc`	An object of class `H5IdComponent` representing a H5 location identifier (file or group). See `H5Fcreate`, `H5Fopen`, `H5Gcreate`, `H5Gopen` to create an object of this kind.
`name`	The name of the link to be checked.

Interface to the HDF5 C-library libhdf5. See http://www.hdfgroup.org/HDF5/doc/RM/RM_H5L.html for further details.

If name consists of a relative path containing group names, the function H5Lexists checks recursively if the links exists which is a different behaviour to the C-function.

H5Lexists returns boolean TRUE if the link exists and FALSE otherwise.

H5Lget_info returns a list with the entries of the C-structure H5L_info_t.
