Thanks Lehua, actually Yes.

Consider we will have a try for hashmap way and will keep you posted.

Can we fast continue if args length not equal arglist length before this 
loop:

   if (args lengh != arglist.length ())
     continue;

   for (k = 0; args[k].base_type != NUM_BASE_TYPES; k++)
   {
     ...
