[Pyrex] Re: Pyrex Header Wrapping

[Adam McCarthy]

I am currently wrapping the current header to implement a barcode
scanner SDK in a python program.  I am currently stuck with the
following error:

ScanAPI.pyx:39:38: C function definition not allowed here

But afaik, I am not defining a function.

This is the original C header:
