H5P_SET_NLINKS sets the maximum number of soft or user-defined link traversals allowed,
nlinks, before the library assumes it has found a cycle and aborts the traversal. This value is set in the link access property list
The limit on the number soft or user-defined link traversals is designed to terminate link traversal if one or more links form a cycle. User control is provided because some files may have legitimate paths formed of large numbers of soft or user-defined links. This property can be used to allow traversal of as many links as desired.
