How to find number of shells belongs to current solid in creo ?

Hi All,

I am implementing Creo API for finding Shells from given solid.I have written following code.

ProSldsurfaceShellorder *shell_order;
ProSldsurfaceShellface *shell_faces;

/*---------------------------------------------------------------------*\
List the shell members of this solid
\*---------------------------------------------------------------------*/

ProSldsurfaceShellsAndVoidsFind(*mProSolid,&shell_order,&shell_faces);

It works fine for me. It gives correct result,but only problem is that I cant get how many number of shells are found.

Means I could not get length of array shell_order. shell_order contains information for each shell.

So is ther any way to find out length of this array shell_order.

thanks in adavance.
