       bson_iter_utf8 - bson_iter_utf8()


          #define BSON_ITER_HOLDS_UTF8(iter) (bson_iter_type ((iter)) == BSON_TYPE_UTF8)

          const char *
          bson_iter_utf8 (const bson_iter_t *iter, uint32_t *length);


       · iter: A bson_iter_t.

       · length: An optional location for the length of the resulting UTF-8 encoded string.


       The  bson_iter_utf8()  function  shall  retrieve  the contents of a BSON_TYPE_UTF8 element
       currently observed by iter.

       It is invalid to call this function while observing an element other than BSON_TYPE_UTF8.


       A UTF-8 encoded string that has not been modified or freed.

       It is suggested that the caller validate the content is valid UTF-8 before using  this  in
       other  places.  That  can  be  done  by  calling  bson_utf8_validate()  or  validating the
       underlying bson_t before iterating it.

       Note that not all  drivers  use  multi-byte  representation  for  \0  in  UTF-8  encodings
       (commonly  referred  to  as modified-UTF8). You probably want to take a look at the length
       field when marshaling to other runtimes.
