H5Lcopy
copies the link
specified by src_name
from the file or group specified by src_loc_id
to the file or group specified by dest_loc_id
.
The new copy of the link is created with the name dest_name
.
If dest_loc_id
is a file identifier,
dest_name
will be interpreted relative to
that file’s root group.
The new link is created with the creation and access property lists
specified by lcpl_id
and lapl_id
.
The interpretation of lcpl_id
is limited in the manner
described in the next paragraph.
H5Lcopy
retains the creation time and the target of
the original link.
However, since the link may be renamed, the character encoding
is that specified in lcpl_id
rather than that of
the original link. Other link creation properties are ignored.
If the link is a soft link, also known as a symbolic link, its target is interpreted relative to the location of the copy.
Several properties are available to govern the behavior of
H5Lcopy
.
These properties are set in the link creation and access property lists,
lcpl_id
and lapl_id
, respectively.
The property controlling creation of missing intermediate groups
is set in the link creation property list with
H5Pset_create_intermediate_group
;
this function ignores any other properties in the link creation
property list.
Properties controlling character encoding, link traversals, and
external link prefixes are set in the link access property list with
H5Pset_char_encoding
,
H5Pset_nlinks
, and
H5Pset_elink_prefix
.
H5Lcopy
does not affect the object that the link points to.
H5Lcopy
cannot copy hard links across files as a hard link
is not valid without a target object;
to copy objects from one file to another, see
H5Ocopy
.
