Function Documentation

pack_strings()

std::vector< const char * > DiFfRG::hdf5::detail::pack_strings ( const std::string * src, std::size_t n )

inline

Pack a contiguous span of std::string into the C array-of-cstr form HDF5 expects for variable-length string writes.

read_vlen_strings()

void DiFfRG::hdf5::detail::read_vlen_strings ( hid_t dset, hid_t , hid_t , hid_t mem_type, std::string * dst, std::size_t n )

inline

Read variable-length strings into a span. The HDF5 library allocates a fresh C string per element; we copy into std::strings and reclaim. dset is the dataset id; we always pass H5S_ALL for both memory and file selection but build an explicit dataspace describing the memory buffer for H5Treclaim (which rejects H5S_ALL).
