how to resize with pjlib?

[nigelcz@xxxxxxxxxxx (Nigel Hsiung)]

Hi list,

I've got a few questions - 

1. What is the pjlib equivalent to a realloc()?
2. Can i do this - 
    
    char str1[32] = {"123456"}; 
    char str2[32] ={"123456789012345"};
    char str3[32] ={"1234"};
    char str4[32] ={"1234678"};

    pj_str_t  pj_string;
    
    //1st call
    pj_strdup2_with_null(pool, &pj_string, str1); // no problem here
    
    //2nd call 
    if(pj_string.slen > strlen(str2))
         pj_strcpy2(&pj_string, str2);    //no problem here too
    else
        pj_strdup2_with_null(pool, &pj_string, str2); // ok to call pj_strdup2 again? 

   //3rd call with str3 ...
    
   //4th call with str4 
   // cannot use pj_string.slen to decide whether to pj_strcpy or pj_strdup, right?
        
    Please help!

thanks,
Nigel
