Re: problem about snmpset

That's easy: make a break :)
(After each case block)

Hi:
        I have a problem about snmpset,when I set only one variable,all the values of variables are changed .


        I want to change the value of only one variable,what can I do to solve the problem? Looking forward for your help!

 

  Here is parts of my program,"example_int"is a global variable:

 
 case DOWNSNDPACK:
        long_ret = example_int;
        *write_method = write_exampleint;
        return (u_char *) & long_ret;
     
  case DOWNRCVPACK:
        long_ret = example_int;
        *write_method = write_exampleint;
        return (u_char *) & long_ret;
        
    case DOWNFLOW:
        long_ret = example_int;
        *write_method = write_exampleint;
        return (u_char *) & long_ret; 
 
    case CPURATE:
        strcpy(string, example_str);
        *var_len = strlen(string);
 *write_method = write_examplestr;
        return (u_char *) string;
        
 int  write_exampleint(int action,
                 u_char * var_val,
                 u_char var_val_type,
                 size_t var_val_len,
                 u_char * statP, oid * name, size_t name_len)
{
    #define MAX_EXAMPLE_INT 100
    static long     intval;
    static long     old_intval;
    
    switch (action) {
    case RESERVE1:
        if (var_val_type != ASN_INTEGER) {
            DEBUGMSGTL(("example", "%x not integer type", var_val_type));
            return SNMP_ERR_WRONGTYPE;
        }
        if (var_val_len > sizeof(long)) {
            DEBUGMSGTL(("example", "wrong length %x", var_val_len));
            return SNMP_ERR_WRONGLENGTH;
        }

        intval = *((long *) var_val);
        if (intval > MAX_EXAMPLE_INT) {
            DEBUGMSGTL(("example", "wrong value %x", intval));
            return SNMP_ERR_WRONGVALUE;
        }
        break;

    case RESERVE2:
        break;

    case FREE: 
        break;

    case ACTION:
        old_intval = example_int;
        example_int = intval;
        break;

    case UNDO:
        example_int = old_intval;
        break;

    case COMMIT:
        break;

    }
    return SNMP_ERR_NOERROR;
}
