How to access symbol when its dimensionality is not known till runtime (About to giveup)

[Christopher M. Lusardi]

Hi,

Is it possible to access the actual value of a symbol at runtime when
you don't know it's definition till then. The symbol can be a variable,
a 1 dimensional array, a 2 dimensional array, or a 3 dimensional array?

If this is possible can you post example code for each case.

(Background: The compiler complains if I just use pointers with nested "if"
statements complaining 3 of the 4 assignments are not defined [identifier
is undefined]. I'm using this code on SGI machines and object code doesn't
contain dimensionality information, only the number of elements [obtained
through the system command dwarfdump on the object code].)

Thank you,
Christopher Lusardi

Is this C or C++ ?

If you are using C, there are other ways to do what (I think) you're
trying to do.

Don't let us guess, what exactly are you trying to do ? There may be a
standards compliant way to do it.
