Conversion method for PyUnicodeObject type to PyBytesObject type

[mathan kumar]

A variable whose data type is PyUnicodeObject needs to be passed to a
function as an argument whose data type should be PyBytesObject type

example :
function (PyByteObject* a){
.operations
}
PyUnicodeObject *p = somevalue;
function((PyBytesObject *)p);

ouptut: Got a Bus Error.

 A variable whose data type is PyUnicodeObject checked whether it is a
 UnicodeObject type.
 Got output as false

 example :

 PyUnicodeObject *p;
 if (PyUnicode_Check(path)) {
 printf(\nTrue.\n);

 }
 else {
 printf(\nfalse.\n);
 }

 output: false


Doesn't surprise me at all. Could you make sure this is the code you are
using? Especially the names 'p' and 'path'? And that you are initialising
neither of the two in your code?

Tat was a typo mistake instead of *p pls consider *path as follows.

PyUnicodeObject *path;
if (PyUnicode_Check(path)) {
printf(\nTrue.\n);

}
else {
printf(\nfalse.\n);
}

But i m getting following errors while building that though i havent changed

Any idea why?
