c-node and arbitrary erlang term

[Roberto Ostinelli]

dear all,

i am currently sending a message from a c-node to an erlang node using  
the following:

char *e_headers = "[{one, 1}, {two, 2}]";
erlterm = erl_format("~s", e_headers);
erl_reg_send(fd, "testc", erlterm);
erl_free_term(erlterm);
free(e_headers);

fd being the file descriptor. this works without any issues, and as  
expected on the process testc i get the string "[{one, 1}, {two, 2}]".

however, since the string "[{one, 1}, {two, 2}]" is already in erlang  
format, i read from erl_format specs <http://erlang.org/documentation/doc-5.5.3/lib/erl_interface-3.5.5.3/doc/html/erl_format.html 
 > that i could use:

~w - Arbitrary Erlang term

however, if i change in the above code the line to:

erlterm = erl_format("~w", e_headers);

i get a bus error and my c-node crashes.

i could of course parse the string and re-build an erlang term from  
the incomed string, however this is obviously something i want to  
avoid. what am i missing?

thank you,

r.
