No - just cast the var_val parameter accordingly.
>From mibII/route_write.c:

     case IPROUTEMETRIC1:
         if ( action == RESERVE1 ) {
             if ( var_val_type != ASN_INTEGER)              [value
must be an integer]
                 // error

             long val  =   *((long *)var_val);
[extract the new value]

             if ( val < -1 )
 [is this new value valid]
                 // error
         }


Don't get confused by the var_val being 'char *'
It's probably better to think of this as 'void *'
It's a generic pointer, that points to the new value.
