  23    kind of symbol.

  26    symbol being requested.  SYM_TYPE is the new symbol's C type;

  28    zero.  If SUBSTITUTION_NAME is not NULL, then a reference to this

  30    of a variable of the given name.  Otherwise, for symbols having
  31    an address (e.g., functions), ADDRESS is the address.  FILENAME

  33    is not known, FILENAME can be NULL and LINE_NUMBER can be 0.
