Warning: blatant hack below; just for fun.
You can put verbatim C code snippets in Cython by abusing cdef extern.
Here is an example that illustrates doing this to wrap some C++ code.
I wanted to put the verbatim C++ code "a[b]=c" in, so I did it like
so. You
could put any C/C++ code inside that macros though, not just a[b]=c.
cdef extern from "vector.h":
ctypedef struct intvec "std::vector<unsigned int>":
int get_entry "operator[]"(int n)
intvec intvec_factory "std::vector<unsigned int>"(int len)
cdef extern from "":
void DEFINE_SET "#define SET(a,b,c) a[b]=c; //"()
void SET(intvec, int, int)
DEFINE_SET()
cdef intvec v = intvec_factory(10)
SET(v,2,399283)
print v.get_entry(2)
Obviously you should never do this :-)
