Question

I have some C source code and want to wrap it in Cython. Now, the problem is, that there is a structure called print, and externing it throws a syntax error.

cdef extern from "foo.h":
    struct print:
        # ...

Same problem would appear when an attribute or a function or alike is called like a keyword.

cdef extern from "foo.h":
    struct foo:
        bint print
    print(char*, int)

Is there a way to work around this, without modifieng the source? Maybe some technique that replaces a proxy-name with the real-name in the source-file ?

Answer 1

I think the solution you are looking for is something along the lines of:

cdef extern from "foo.h":
    struct print "MY_print":
        double var "MY_var"

print.var will then be defined by:

MY_print.MY_var

This way you can rename structs, functions, unions and enums from the header file. The names are converted when Cython compiles your code into C code.

The relevant part of Cython documentation can be found here.
