SUBROUTINE h5oincr_refcount_f(obj_id, hdferr)
INTEGER(HID_T), INTENT(IN) :: obj_id
INTEGER , INTENT(OUT) :: hdferr
|IN: Object identifier; may be a group, named datatype, or dataset identifier|
H5O_INCR_REFCOUNT increments the hard link reference count for an object. It should be used any time a user-defined link that references an object by address is added. When the link is deleted, H5O_DECR_REFCOUNT should be used.
An object’s reference count is the number of hard links in the file that point to that object. See the “Programming Model” section of the HDF5 Groups chapter in the HDF5 User’s Guide for a more complete discussion of reference counts.
If a user application needs to determine an object’s reference count, an H5O_GET_INFO call is required; the reference count is returned in the
rc field of the
Warning: This function must be used with care!
