hdf_get_valuevf(3)

💖 hdf_get_valuevf(3) 💖

okay bestie, welcome to the manual page for hdf_get_valuevf — she lives in util/neo_hdf.h and she is, lowkey, the varargs girlie of the HDF crew. pull up a chair 🫶

✨ NAME ✨

hdf_get_valuevf — return the value of a node in the data set 💅

🌈 SYNOPSIS 🌈

#include <util/neo_hdf.h>

char* hdf_get_valuevf (HDF *hdf, const char *namefmt, va_list ap);

no cap, that's the whole signature. she takes a va_list and she slays.

🎀 ARGUMENTS 🎀

• hdf — the dataset node to start from. this is your starting point, your home base, your main character energy origin story 💫
• namefmt — the format string. yes bestie, a printf-style format string, she's flexible like that ✨
• ap — a va_list of varargs. it's giving "I already got my args packed up, just hand me the list" 📦

🦋 DESCRIPTION 🦋

so here's the tea, bestie ☕

hdf_get_valuevf walks the data set that hdf points to, using namefmt printf-expanded with the varargs in ap, and then returns the string value hanging out at that spot. if it's not there? you get NULL. that's it, that's the whole vibe. 🕳️

and here's the part that makes her different from her sister hdf_get_value — there is no default value possible with this one. none. zero. nope. hdf_get_value will let you hand over a fallback if the node's missing, but hdf_get_valuevf does NOT do that. it's all or nothing, iconic behavior honestly 👑

💀 RETURN VALUE 💀

None

not me reading the docs and the return value section just says None 😭 the description clearly says it returns a string value or NULL, but the manpage itself says None, and bestie I am not editing the source material. keeping the facts exactly as they are, periodt. 📌
