rte_argparse(3)

💖 rte_argparse 💖

okay bestie, gather round, because today we're learning about rte_argparse — it's a Library Functions Manual moment, she's a 3, she's from the rte_argparse(3) page, and honestly? iconic.

✨ NAME ✨

rte_argparse — that's it, that's the name, she's literally just a struct serving cunt and holding your config 🫶

---

🌸 SYNOPSIS 🌸

#include <rte_argparse.h>

🎀 Data Fields 🎀

here's the whole cast, in order, no one gets cut:

• const char * prog_name
• const char * usage
• const char * descriptor
• const char * epilog
• bool exit_on_error
• bool ignore_non_flag_args
• rte_arg_parser_t callback
• void * opaque
• void(* print_help )(const struct rte_argparse *obj)
• void * reserved [15]
• struct rte_argparse_arg args []

---

🦋 DESCRIPTION 🦋

so basically this struct is where argparse keeps all her configuration. that's the whole vibe. 💅

she's defined at Definition at line 150 of file rte_argparse.h.

💜 FIELD DOCUMENTATION 💜

okay now the main character energy — one field at a time, no skipping, bestie, fr fr:

• const char* prog_name — the program's name. this one absolutely must not be NULL, no exceptions, don't try it. 🚫

Definition at line 152 of file rte_argparse.h.

• const char* usage — how you use the program. also must not be NULL, periodt.

Definition at line 154 of file rte_argparse.h.

• const char* descriptor — explains what the program actually does. this one could be NULL, she's optional, lowkey chill like that. 😌

Definition at line 156 of file rte_argparse.h.

• const char* epilog — the text that lives at the bottom of the help output. could be NULL too, no pressure. 💖

Definition at line 158 of file rte_argparse.h.

• bool exit_on_error — whether to exit when there's an error.

Definition at line 160 of file rte_argparse.h.

• bool ignore_non_flag_args — makes her behave like getopt and move non-flag args to the end, ignoring them otherwise. but — heads up — if this flag is specified, no positional args are allowed. not even one. 🫠

Definition at line 164 of file rte_argparse.h.

• rte_arg_parser_t callback — the user callback that does the actual parsing of arguments.

Definition at line 168 of file rte_argparse.h.

• void* opaque — the opaque thingy that gets used to invoke the callback. mysterious, we love her. 🙈

Definition at line 170 of file rte_argparse.h.

• void(* print_help) (const struct rte_argparse *obj) — a function pointer for printing usage when -h is passed. and if this is NULL, the default printing function steps in and handles it. ✨

Definition at line 175 of file rte_argparse.h.

• void* reserved[15] — reserved field, saved for future extension. she's just vibing in the back waiting for her moment. ⭐

Definition at line 177 of file rte_argparse.h.

• struct rte_argparse_arg args[] — the arguments configuration. must be ended with ARGPARSE_ARG_END() — do not forget this, bestie, it's giving unfinished sentence energy and the parser will NOT forgive you. 😭

Definition at line 179 of file rte_argparse.h.
