Hi Marc,
You could use H5Literate with the following iterator:
herr_t findExternalLink(hid_t g_id, const char * name, const H5L_info_t
* info, void * op_data)
{
if (info->type == H5L_TYPE_EXTERNAL && !strcmp(name, (char *)op_data))
{
return 1;
}
return 0;
}
And you call it with:
int idx = 0;
char * nameToFind = "foo";
err = H5Literate(obj_id, H5_INDEX_NAME, H5_ITER_INC, &idx,
findExternalLink, nameToFind);

Hi all,
I'd link to check a node exists before traversing it.
This node, child of a group G, is an external link.
Here's a tree example output using h5dump:
HDF5 "sqnz_unstruct_2dom_TOP.hdf" {
FILE_CONTENTS {
group /
group /base1
dataset /base1/ data
group /base1/dom1
dataset /base1/dom1/ file
ext link /base1/dom1/ link -> sqnz_unstruct_2dom_dom1_SUB.hdf
/base1/dom1
dataset /base1/dom1/ path
group /base1/dom2
dataset /base1/dom2/ file
ext link /base1/dom2/ link -> sqnz_unstruct_2dom_dom2_SUB.hdf
/base1/dom2
dataset /base1/dom2/ path
}
}
I just want to test that ' link' is there, I *don't* want the lib to
traverse it.
Using H5Oget_info, I cannot check if it's an external link.
Using H5Lexists, I cannot stop the traversal to the actual linked-to
node,
which fail if link prefix property is not set.
We used to do that with H5Gget_objinfo which is said to be obsolete...
Any idea ?
