hey.

how is it possible to print out an array (T\_ARRAY) in a C-method?

example

I want to get the instance methods via the corresponding c method. the  
method returns T\_ARRAY.  
VALUE es = rb\_class\_instance\_methods(1, args, CLASS\_OF(targetcl));

is there something like:  
for(int i = 0; i\<RARRAY\_LEN(es); i++)  
{  
printf(“content of array element %s”,es[i]);  
}  
?? 🙂  
I know that the content of the array element is a (ruby) string.

thx for your help in advance

rb\_ary\_entry(n) returns the VALUE at index n.  
StringValuePtr(obj) returns a pointer to the C string in a String  
object.
