 Forums >>  IDA Pro  >>  Convert local variable to array in IDA Python

Topic created on: June 1, 2012 17:36 CDT by cr0w .

Does anyone know if IDAPython API (or IDC) allows us to convert a local byte variable to a byte array?  I cannot seem to find any API calls that will do it.  For example, say we have var_1, which is a byte.  I want to make it a byte array of size 6.  In IDA, we simply right click and adjust the size in the stack frame.

So far in script, I can get the variable and offset, and I can get the current size as well, using GetFrame, GetMemberOffset, and GetMemberSize.  If I have already converted one to an array, GetMemberSize returns the correct size.  However, there is no SetMemberSize function.

A few ways I've tried:

MakeArray - nothing seems to happen, and I'm not even sure where this would make it.  You pass it ea, or the linear offset.  This wouldn't apply to a functions stack frame.

SetMemberType - tried this thinking I could just set the type with nitems = 6, but with no luck.

Suggestions?
