NAME
hdf_set_symlink - Set part of the tree to link to another
SYNOPSIS
#include <util/neo_hdf.h>
NEOERR *hdf_set_symlink (HDF *hdf, const char *src, const char *dest);
ARGUMENTS
hdf -> the dataset node
src -> the source node name
dest -> the destination node name (from the top of the
dataset, not relative names)
DESCRIPTION
hdf_set_symlink creates a link between two sections of an HDF dataset.
The link is "by name" hence the term "symlink". This means that the
destination node does not need to exist. Any attempt to access the
source node will cause the function to walk to the dest node, and then
continue walking from there. Using symlinks can "hide" values in the
dataset since you won’t be able to access any children of the linked
node directly, though dumps and other things which access the data
structure directly will bypass the symlink. Use this feature sparingly
as its likely to surprise you.
RETURN VALUE
None
