	size_t len

length of value. semantic is depended on syntax:

* primitive syntax:
  
  #. INTEGER zero for usual native 'int' or number of bits used.
  
  #. LONG_INT, CHAR_STRING, OCT_STRING, REAL number of used octets;
  
  #. OBJECT IDENTIFIER number of sub-ids, which sub-id has usual for current architecture size of 'int';
  
  #. BIT_STRING number of bits;

* compound syntax: number of sub-values, This field should be one or zero (for non-complete values) for CHOICE and TAGGED syntaxes.

	char* path

Path to this value from root of some container. It is valid ONLY inside asn_walk_depth function. Root container is a container which was passed to asn_walk_depth. Use asn_get_value_path from walk_func to obtain this path
