Name: H5Topen
Signature:
hid_tH5Topen(hid_t loc_id, const char * name )
Purpose:
Opens a named datatype.
Description:
H5Topen opens a named datatype at the location specified by loc_id and returns an identifier for the datatype. loc_id is either a file or group identifier. The identifier should eventually be closed by calling H5Tclose to release resources.
Parameters:
Returns:
Returns a named datatype identifier if successful; otherwise returns a negative value.
