H5O_GET_COMMENT retrieves the comment for the specified object in the buffer comment . The target object is specified by an identifier, object_id . The size in bytes of the buffer comment , including the NULL terminator, is specified in bufsize . If bufsize is unknown, a preliminary H5O_GET_COMMENT call with the pointer comment set to NULL will return the size of the comment without the NULL terminator. If bufsize is set to a smaller value than described above, only bufsize bytes of the comment, without a NULL terminator, are returned in comment . If an object does not have a comment, the empty string is returned in comment . |
