Quick question. If I want to return a char * from Cython to Python as a
string, should I be freeing the original char * or not? In other words,
when Cython does the implicit conversion from char * ---> string, does it
create a Python object and strcpy the char * into its data, or does it copy
the pointer?
Here's some code to make this clearer:
cdef class MyStringHolder:
cdef char *my_str
...
cpdef add_to_set(object set):
// Is this necessary or is this a memory leak?
cdef char * str_cpy = <char*>malloc(strlen(my_str) + 1)
strcpy(str_cpy, my_str)
// Should this just be set.add(my_str)?
set.add(str_cpy)
Thanks!
