BSDE_PARSE_RULE(3)

💖 BSDE_PARSE_RULE(3) 💖

okay bestie, welcome to the BSDE_PARSE_RULE(3) page from the Library Functions Manual — it’s giving file system firewall rule parsing, and we’re gonna get you comfy with it ✨

---

🌸 NAME 🌸

bsde_parse_rule, bsde_parse_rule_string — parse file system firewall rules

---

🫶 LIBRARY 🫶

File System Firewall Interface Library (libugidfw, -lugidfw) — iconic, no cap 💅

---

✨ SYNOPSIS ✨

#include <ugidfw.h>

int
bsde_parse_rule(int argc, char *argv[],
    struct mac_bsdextended_rule *rule, size_t buflen, char *errstr);

int
bsde_parse_rule_string(const char *string,
    struct mac_bsdextended_rule *rule, size_t buflen, char *errstr);

---

💅 DESCRIPTION 💅

okay so the bsde_parse_rule() function parses an argument vector (e.g. argv as passed to main()) into rule. If an error occurs 😭, *errstr is filled in with the error string (up to errlen characters, including the terminating NUL). yes bestie, that’s the exact wording — periodt.

The bsde_parse_rule_string() function is identical to bsde_parse_rule(), except that it parses a single string rather than an array of arguments. lowkey convenient, highkey slay 🦋

---

🔥 RETURN VALUES 🔥

The bsde_parse_rule_string() and bsde_parse_rule() functions return 0 if successful; otherwise the value -1 is returned and the value of *errstr is filled in as documented in “DESCRIPTION”. no cap — 0 means it ate, -1 means check the error string 💀
