C/C++ however, do have pointers. In order to make Python compatible with C/C++ functions that require or return pointers the Ctypes library introduces the Pointer data type in Python. We can also use them normally in Python like we would in C/C++. The easiest way to create a pointer in...
We can dereference a pointer variable using a*operator. Here, the*can be read as'value at'. Since you have now learned the basics of Pointers in C, you can check out someC Pointer Programswhere pointers are used for different use-cases. ...
We will use thesocketmodule, which comes built-in with Python and provides us with socket operations that are widely used on the Internet, as they are behind any connection to any network. Please note that there are more reliable ways totransfer files with tools likersyncorscp. However, the...
Back to our Python file now. We will need to first explicitly define the return type of thegetArray()function as a “integer pointer” using the restype attribute (part of the function signature in ctypes). (We usually need to do this with functions that return pointers in C) 1 2 3 ...

Themalloc()function reserves a block of memory of the specified number of bytes. And, it returns apointerofvoidwhich can be casted into pointers of any form. Syntax of malloc() ptr = (castType*)malloc(size); Example ptr = (float*)malloc(100*sizeof(float)); ...

Using Python API with USearch Want to use it in Python with USearch? You can wrap the raw C function pointers SimSIMD backends into a CompiledMetric and pass it to USearch, similar to how it handles Numba's JIT-compiled code. from usearch.index import Index, CompiledMetric, MetricKind, Me...

A Deque is a double-linked list that has a larger memory capacity than a regular list, with two pointers per node instead of one. Although this difference is negligible, users can add and remove elements from both ends of the Deque. ...
