Warning loadline: Data type ULONG,UCHAR,... unknown which are used in h-file

Hello everyone,

I'm trying to load a shared library, called Gen3.dll, into MATLAB. The corresponding header file is gives some warnings:

" Type 'ULONG' was not found. Defaulting to type error." The corresponding line was: typedef struct{ ulong ulValidData;...}

Sam error appears for uchar and ushort.

How do I resolve this issue? (Note, I have not developped the dll nor the header, so my resources are somewhat limited...)

I found that these are the declarations used in C++, but the correct syntax in C is unsigned long, etc.

That resolved the warning.
