[svn-r8465] Purpose:
Add more C++ wrappers - incrementally check-in Description: Added wrapper for many C property list functions and added Doxygen documentation to existing C++ functions in these files. This is an incremental check-in to preserve the code, corresponding tests will follow in a few weeks. For H5PropList.h and H5PropList.cpp, added C++ wrappers for: H5Pexist H5Pclose_class H5Pget H5Pget_size H5Pget_class_name H5Pget_nprops H5Pset H5Pisa_class H5Premove H5Pequal H5Pget_class_parent For H5FaccProp.h and H5FaccProp.cpp, added C++ wrappers for: H5Ps[g]et_driver H5Ps[g]et_family_offset H5Ps[g]et_fapl_core H5Ps[g]et_fapl_family H5Ps[g]et_fapl_stream H5Ps[g]et_sieve_buf_size H5Ps[g]et_meta_block_size H5Ps[g]et_alignment H5Ps[g]et_multi_type H5Ps[g]et_fclose_degree H5Pset_fapl_stdio H5Pset_fapl_split H5Pset_fapl_log H5Pset_fapl_sec2 For H5FcreatProp.h and H5FcreatProp.cpp, added C++ wrappers for: H5Pfill_value_defined H5Premove_filter H5Pget_filter_by_id H5Pmodify_filter H5Pall_filters_avail H5Pset_shuffle H5Ps[g]et_alloc_time H5Ps[g]et_fill_time H5Pset_fletcher32 For H5DxferProp.h and H5DxferProp.cpp, added C++ wrappers for: H5Ps[g]et_dxpl_multi H5Ps[g]et_small_data_block_size H5Ps[g]et_hyper_vector_size H5Ps[g]et_edc_check Platforms: SunOS 5.7 (arabica) Linux 2.4 (eirene) SunOS 5.8-64 (sol)
