Hello,
First the problem that i have. Right now, when i get a string back from
a C function, i have to do 2 copies of it:
ffi.cdef("""
const char *getString(...);
""")
tmp = ffi.string(clib.getString(...)) # 1st copy
pystring = tmp.decode('utf-8') # 2nd copy
So i thought why not use an ffi.buffer on it and do the decoding
directly on the buffer:
cstr = ffi.new('char []', 'abcd')
b = unicode(ffi.buffer(cstr), 'utf-8')
Above works.
But the problem is that in C a function that returns an array cannot be
declared. So i cannot do a:
b = unicode( ffi.buffer( clib.getString(...) ) ,'utf-8')
because it'll only return the first character of getString, due to being
declared as a 'char*'.
Is there any way in CFFI to declare a function as returning a 'char[]'
so as a buffer can be directly used on its results?
Thank you.
l.
