gd_nframes64(3)

💖 gd_nframes64 — report the size of a Dirfile, with largefile support 💖

okay bestie, so this one lives in the GETDATA manual, section 3, and it's literally just the big-girl version of gd_nframes(3). let's get into it 🦋

✨ SYNOPSIS ✨

#define GD_64BIT_API
#include <getdata.h>

gd_off64_t gd_nframes64(DIRFILE *dirfile);

no cap, that #define up top is doing a LOT of heavy lifting here. do not skip it. 🙈

🌸 DESCRIPTION 🌸

so the whole point of this function is that it's the same deal as gd_nframes(3), except it uses a 64-bit offset type (gd_off64_t) whenever one is actually available — and it does that regardless of how big off_t happens to be on your system. main character energy fr fr. 👑

lowkey important: this function is only guaranteed to be available if GD_64BIT_API is defined before you include getdata.h. that's not a vibe, that's a rule. define it first or don't come crying to me. 😭

and here's the tea on how it relates to the 32-bit one:

• if off_t is already a 64-bit type, then this function and gd_nframes(3) are the same thing. same function, no drama. ✨
• if off_t is not 64-bit, then it flips: gd_nframes(3) becomes the version of this function that uses a 32-bit off_t. iconic behavior honestly. 💅

so basically they're two sides of the same coin and which one you're holding depends on your off_t. slay. 🎀
