👑 Field Documentation 👑

char name[RTE_MBUF_DYN_NAMESIZE]

Name of the field. Yes bestie, it needs a name, everything deserves one. 💖

Defined at line 87 of the file rte_mbuf_dyn.h.

size_t size

The number of bytes to reserve. That's the bag you're setting aside for this field — reserve exactly that many bytes, no cap. ✨

Defined at line 88 of the file rte_mbuf_dyn.h.

size_t align

The alignment constraint (power of 2). So like 1, 2, 4, 8, 16… powers of two only, please. Also it literally spells out "(power of 2)" in the docs so this is not me guessing, this is canon. 🔥

Defined at line 89 of the file rte_mbuf_dyn.h.

unsigned int flags

Reserved for future use, must be 0. That's it, that's the whole lore — it's a placeholder, so leave it at 0 and let future-us cook. 🙈

fr fr: if you set this to anything but 0, that's you going off-script on a field the docs say is reserved. Don't. 🫶

Defined at line 90 of the file rte_mbuf_dyn.h.
