Name: H5Fget_obj_count
Signature:
ssize_t H5Fget_obj_count( hid_t file_id, unsigned int types )
Purpose:
Returns the number of open object identifiers for an open file.
Description:
Given the identifier of an open file, file_id, and the desired object types, types, H5Fget_obj_count returns the number of open object identifiers for the file.

To retrieve a count of open identifiers for open objects in all HDF5 application files that are currently open, pass the value H5F_OBJ_ALL in file_id.

The types of objects to be counted are specified in types as follows:

H5F_OBJ_FILE Files only
H5F_OBJ_DATASET Datasets only
H5F_OBJ_GROUP Groups only
H5F_OBJ_DATATYPE   Named datatypes only
H5F_OBJ_ATTR Attributes only
H5F_OBJ_ALL All of the above
(I.e., H5F_OBJ_FILE | H5F_OBJ_DATASET | H5F_OBJ_GROUP | H5F_OBJ_DATATYPE | H5F_OBJ_ATTR )
H5F_OBJ_LOCAL Restrict search to objects opened through current file identifier.

Multiple object types can be combined with the logical OR operator (|). For example, the expression (H5F_OBJ_DATASET|H5F_OBJ_GROUP) would call for datasets and groups.

Parameters:
Returns:
Returns the number of open objects if successful; otherwise returns a negative value.
