I have a C/C++ programming question. It is not
exactly related to Performer, but I know you are all
experts in the area, so hopefully someone can help me
out.

I have to use an API function with the following
prototype:

void fun(const char *fnames[][2]);

//fnames is supposed to be a 3D array (can be thought
of as two arrays of pointers with each pointer
pointing to a string of characters).
//For example, fnames can be used to store the names
of students in two workshops. The number of students
in the two //workshops may or may not be the same.
The names of the students can be of length 256
characters.

How can I setup the argument variable (fnames) to use
fun()?

Here is what I've tried but didn't work:
----------------------------------------
I allocated a variable of the following type and gave
it some values:
char **temp[2];

Then, I called the function as follows, but I couldn't
seem to get it to work:
fun(temp); //doesn't work, typecast error
fun((const char **[2])temp); //doesn't work, typecast
error
fun((const char ***)temp); //doesn't work, typecast error

=====
Thanks,
