dynevent_arg_add(9)

🌸 NAME 🌸

hey bestie, welcome to the dynevent_arg_add(9) manual page from the Kernel API Manual ✨

dynevent_arg_add — Add an arg to a dynevent_cmd 💅

---

✨ SYNOPSIS ✨

int dynevent_arg_add (struct dynevent_cmd *cmd , struct dynevent_arg
       *arg , dynevent_check_arg_fn_t check_arg );

---

🎀 ARGUMENTS 🎀

• cmd — A pointer to the dynevent_cmd struct representing the new event cmd. literally the main character struct here 👑
• arg — The argument to append to the current cmd. this is the little string bestie getting added 🦋
• check_arg — An (optional) pointer to a function checking arg sanity. optional, but if it's there it's doing a vibe check on your arg 😌

---

🧚 DESCRIPTION 🧚

okay so here's the tea: this function appends an argument to a dynevent_cmd. the argument string will be appended to the current cmd string, followed by a separator, if applicable. before the argument is added, the check_arg function, if present, will be used to check the sanity of the current arg string. no cap, that's the whole flow 💖

the cmd string and separator should be set using dynevent_arg_init before any arguments are added using this function. like, set it up first bestie, that's the assignment 🎀

---

⭐ RETURN ⭐

0 if successful, error otherwise. slay when it's 0, and if it's an error, welp 😭
