HPL_sum(3)

✨ HPL_sum ✨

okay bestie, gather round, we're doing a manual page from the HPL Library Functions collection and it's literally called HPL_sum 💖 it's giving "add two things together but make it ✨parallel✨" and honestly? we're obsessed.

🌸 NAME 🌸

HPL_sum — combine (sum) two buffers. that's it. that's the whole job. and she does it flawlessly 💅

---

🦋 SYNOPSIS 🦋

#include "hpl.h"

void HPL_sum( const int N, const void * IN, void * INOUT, const
HPL_T_TYPE DTYPE );

like, copy that signature exactly, don't be cute with it 🙈

---

💜 DESCRIPTION 💜

HPL_sum combines (sum) two buffers. yes queen, that's literally the entire description. she is a specialist. she knows what she is. no notes 🔥

---

👑 ARGUMENTS 👑

• N — (input) const int. on entry, N specifies the length of the buffers to be combined. and N must be at least zero, periodt — no negative lengths, we do not do that here 💀
• IN — (input) const void *. on entry, IN points to the input-only buffer to be combined. she's read-only bestie, hands off, don't even think about writing to her 🫶
• INOUT — (input/output) void *. on entry, INOUT points to the input-output</> buffer to be combined. on exit, the entries of this array contain the combined results ✨ so like, she goes in as one thing and comes out as the sum. main character transformation arc, no cap.
• DTYPE — (input) const HPL_T_TYPE. on entry, DTYPE specifies the type of the buffers operands. you gotta tell her what flavour of numbers you're working with, she's not a mind reader 🎀
