[Gcl-devel] puzzled....

[root]

in o/object.h (line 350) there is the struct:

struct ustring{ 
  ....
  unsigned char *ust_self;
  ....

this appears to be the definition of ust_self, a pointer to a char *array



in gcl-tk/sheader.h (line 109) OBJ_TO_CONNECTION_STATE(x) is defined as
  
#define OBJ_TO_CONNECTION_STATE(x) \
  ((struct connection_state *)(void *)((x)->ust.ust_self))

so it appears that OBJ_TO_CONNECTION_STATE accepts a thing of type
ustring and casts the (char *)array to a (connection_state *)array


yet in sockets.c (line 330) the macro is used with an argument:
 .... (OBJ_TO_CONNECTION_STATE(fd) .....
where "fd" has been used to indicate the "file descriptor" which
is a fixnum.

Further the buffer it tries to write into needs to be of type ustring.

I have 2 questions:
  (a) should sockets.c line 330 read:
       ... (OBJ_TO_CONNECTION_STATE(sfd) ...
       (which means that the argument to the function must change)
  
  (b) how does one allocate a ustring?
