I am writing a Python wrapper to go around a C library. I have encountered a
problem that I have been unable to resolve with
countless web searches.
Several functions in the C library return pointers to dynamically allocated
w_char null terminated strings. I need to copy the
string to a Python variable and call an existing library function that will
free the dynamically allocate memory.
My test code for this is
def Test(fno, item):
func = mylib. MyFunc
func.restype = ct.c_void_p
s = func(fno, item)
result = s
mylib.free(s)
return result
The problem is with the line that sets the result variable. I need this to make
a copy of the dynamically allocated string, not the
pointer to it.
Thanks in advance.
Martin
