Re: Interface To C Struct That Includes An Array

Probably you pass a link to the whole record somewhere where expected only a link to the data field. The other explanation of binary garbage in the string is that you get somwhere a raw uncutted data, because the aiGetMaterialString cuts the 32-bit prefix and corrects the length in aiString field by itself.

It doesn't seems to be a good idea for me to copy a kilobyte of data on every call.

As I can remember, this icon stays for nonprintable characters.

I also notice, that you forget the last argument "unsigned int * flags".
