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
