Toolkit - initializing a ProDwgtable before use?

Compiling some code in MVS2012 that has always compiled for me in the past.   I get these "uninitialzed local variable"  'table' used.   Where table is declared as a pointer to ProDwgTable.   Like ProDwgtable *table;

How would you even initialize such a variable?

 

The call that reference table and that throws this flag is:

tkerr = ProDwgtableRetrieve((ProDrawing)drawing, wName, wPath, 0, point, (ProMdl)solids[0], NULL, table);

 

Thanks for any help!

I ended up just setting these to NULL before use.

Hi @msteffke

 

In C/C++ Program it is always best practice to use NULL Pointers

 

1. Always initialize pointer variables as NULL.
2. Always perform NULL check before accessing any pointer.
