There's no functionality to help with this in htslib. We have a char* text and uint32_t l_text, so the question is what we want:

  1. Const access to the raw data, possibly as a std::string (just because we prefer C++).
  2. Set string
  3. Some interface to solve wish in description with something like
std::string read_group("foo", "SM");

(In [3408]) Implement functions to get/set free text in BamHeader?. As setting the header text modifies underlying data, copy and assignment are now implemented as hard copy (rather than the implicit pointer copy as before). It also means that the bam_hdr_t* is no longer owned by InBamFile?, but is now owned by BamHeader? and destroyed in its destructor.
