Parameters ---------- function : {PyCapsule, ctypes function pointer, cffi function pointer} Low-level callback function. user_data : {PyCapsule, ctypes void pointer, cffi void pointer} User data to pass on to the callback function. signature : str, optional Signature of the function. If omitted, determined from *function*, if possible. Attributes ---------- function Callback function given. user_data User data given. signature Signature of the function. Methods ------- from_cython Class method for constructing callables from Cython C-exported functions. Notes ----- The argument ``function`` can be one of: - PyCapsule, whose name contains the C function signature - ctypes function pointer - cffi function pointer The signature of the low-level callback must match one of those expected by the routine it is passed to. If constructing low-level functions from a PyCapsule, the name of the capsule must be the corresponding signature, in the format:: return_type (arg1_type, arg2_type, ...) For example:: "void (double)" "double (double, int *, void *)" The context of a PyCapsule passed in as ``function`` is used as ``user_data``, if an explicit value for ``user_data`` was not given. r Ncl||||}t||||fSN)_parse_callbacktuple__new__)clsfunction user_data signatureitems r rzLowLevelCallable.__new__Ts6""8Y BB}}S49"=>>>r cBd|j|jS)NzLowLevelCallable({!r}, {!r}))formatrrselfs r __repr__zLowLevelCallable.__repr__Zs-44T]DNSSSr c8t|dS)Nrr __getitem__r!s r rzLowLevelCallable.function]  q)))r c8t|dS)Nr%r!s r rzLowLevelCallable.user_dataar'r c\tjt|dS)Nr)rget_capsule_signaturerr&r!s r rzLowLevelCallable.signaturees#1%2C2CD!2L2LMMMr ctr) ValueError)r"idxs r r&zLowLevelCallable.__getitem__is llr c |j|}nR#t$r}td|d}~wt$r(}td||d}~wwxYw||||S)a Create a low-level callback function from an exported Cython function.
