AnchorNamedescription

Description:
HTML Wrap
classhdf-rm-section

H5G_OPEN2 opens an existing group, name, at the location specified by loc_id.

With default settings, H5G_OPEN2 provides similar functionality to that provided by H5G_OPEN1. The only difference is that H5G_OPEN2 can provide a group access property list, gapl_id.

H5G_OPEN2 returns a group identifier for the group that was opened. This group identifier should be released by calling H5G_CLOSE when it is no longer needed.
