   Hi folks,   
      
   I am a newbie at network programming and have been trying to get the   
   res_search() function to work.  I have searched through many man pages   
   and websites and still keep on getting a segment error.  I am sure the   
   answer is fairly obvious with somone with experience but I can't seem   
   to get it to work.  Here is a copy of the code I am trying to compile.   
      
      
      
   #include    
      
   #define MAXPACKETSIZE IPV6_MAXPACKET   
      
   boolean_t   
   SniffResolver()   
   {   
   	// Arguments   
   	const char dname = "azzmosphere.azzmos.com.au";   
       int type = T_A;   
   	// end arguments   
      
   	int  anslen      = MAXPACKETSIZE;   
   	u_char *answer = malloc(MAXPACKETSIZE);   
   	int ranslen = 0;   
   	   
   	ranslen = res_search(dname, C_IN, type, answer, anslen);   
   	   
   	syslog(LOG_DEBUG, "_res.options = '%d'", _res.options);   
   	syslog(LOG_DEBUG, "ranslen = '%d'", ranslen);   
      
      
   	return TRUE;   
   }   
      
      
   All the headers have been included and seem to be correct and the code   
   does compile correctly.  It does produce a run time error after I   
   compile,   
      
   The debugger message I get is:   
      
   Program received signal EXC_BAD_ACCESS, Could not access memory.   
   Reason: KERN_INVALID_ADDRESS at address: 0xffffffac   
   0x9352839a in res_nsearch_2 ()   
      
      
   which to me would seem that the 'answer' variable is not correctly   
   allocated but I have used both Malloc and tried to defining as 'u_char   
   answer[MAXPACKETSIZE];' both to the same effect.
