将Python结构的地址传递给C函数

Question

I want to pass the address of a structure to a C program. In CI would use something like fun(&vendorRecord). I have tried various forms I have found on the internet but nothing works. Can someone give me a suggestion?

My structure looks like this:

class vendrRecord(Structure):
    _pack_ = 1                                            # pack the struct
    _fields_ = [
        ("vendorListNumber"      ,c_ubyte *(5)),
        ("vendorNumber"          ,c_ubyte *(5)),
        ]

My C structure looks like this:

struct  {
    unsigned char vendorListNumber[5];
    unsigned char vendorNumber[5];
} vendrRecord;

My C prototype looks like this:

void fun(void *record);

My C call looks like this:

fun(&vendrRecord);

Answer 1

VendrRecord = vendrRecord()
fun(byref(VendrRecord))
