jithoosin has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks,
Is there any way by which we could deteremine the size of string variable returned by POPp command ( used in perl embed ). I need this because i use
char string[2058]; strcpy(string , POPp)
. But the problem is some times the string returned (pointer ) by POPp is greater than the size i already allocted. So i want to dynamically allocate the size required. Could any of the monks tell me how to do this.
Thanks
Kiran.

    'perldoc perlapi' says
    POPp

    Pops a string off the stack. Deprecated. New code should provide a STRLEN n_a and use POPpx.

    update: so something like 
    STRLEN n_a;
char* stringy;
stringy = POPpx;

    [download]
    Now n_a contains the length of stringy , and you can do whatever from there.
