Hi ,
I am hitting this very strange issue that i am providing a wrapper
for some hash method that is 192 bit or ( unsigned long long int in
c) .
when i invoke this function from other C code and i run the code it
returns correct hash value , but when i compile it and install it
with setup,py , the result is something totally different.
Is it that when python convert c code into ".so" file it changes data
types of variables??? maybe a bug?
Thanks,
Farshid
here is the code
the method is wrapper for tiger method;
typedef unsigned long long int word64;
typedef unsigned long word32;
typedef unsigned char byte;
void tiger(byte*, word64, word64*);
PyObject *wrap_function(PyObject *self, PyObject *args)
{
word64 result[3];
char *command;
// if (!PyArg_ParseTuple(args, "s",&command))
// return NULL;
//printf("command is %s\n",command);
command = "abc";
tiger((byte*)command,strlen(command),result);
char new_str [48];
sprintf(new_str,"%08X%08X%08X%08X%08X%08X",(word32)(result[0]>>32),
(word32)(result[0]),(word32)(result[1]>>32),(word32)(result[1]),
(word32)(result[2]>>32),(word32)(result[2]));
printf("inside wrap_function %s\n",new_str);
return Py_BuildValue("s",new_str,strlen(new_str));
}
