tomoyo_set_string(9)

💖 NAME 💖

Okay bestie, welcome to tomoyo_set_string(9) from the Kernel API Manual — this one is literally here to queue a string to the struct tomoyo_io_buffer structure. Periodt. 💅

---

✨ SYNOPSIS ✨

void tomoyo_set_string (struct tomoyo_io_buffer *head , const char *string );

---

🫶 ARGUMENTS 🫶

• head — Pointer to struct tomoyo_io_buffer. That's the buffer bestie we're working with. 🎀
• string — String to print. The actual text content, no cap. ✨

---

🌸 DESCRIPTION 🌸

So here's the important tea: string has to be kept valid until head is kfreed. 🚨 That means a char[] allocated on stack memory cannot be passed to this function. Like, do not do it, bestie, it's giving danger.

Use tomoyo_io_printf for char[] allocated on stack memory instead. 💖

🦋 Lowkey crucial: keep string valid until head is kfreed, and do not pass stack-allocated char[] here. For stack-allocated char[], use tomoyo_io_printf. 💅
