The string that is returned from the function
HM_ExtAPI::CADDocumentGetLinkName() should be copied for further use.
If the function succeeds, the return value is the pointer to zero terminated string that
contains the name of the document link. The return value can also be NULL. This usually
means that the document doc is the root document in the assembly hierarchy, or that assembly
hierarchy is not supported by the CAD translator used for loading the model.
Do not attempt to free the returned pointer.
The link name is the name that is used within the assembly to reference the document within
the assembly. The root documents normally do not have the link name.
Requires including hm_extapi.h.
