Ah, the error came from [textfile] not wanting to write an empty  
file.  This works for me with your unchanged C code:

For the outlet, I would bind to a unique receive symbol generated from  
the pointer to the instance of the sys_gui object, then use that  
receive to send the bang in Tcl, receive it in C, then output it out  
the outlet:

  sprintf(buf,"#%lx", (long unsigned int)x);
