parport_ip32_write_control(9)

💅 parport_ip32_write_control(9) 💅

okay bestie, this is a page straight out of the Kernel API Manual, and it’s all about parport_ip32_write_control(9). No cap, it’s giving “tiny function, very specific job” energy. 🦋

---

🎀 NAME 🎀

parport_ip32_write_control — set new contents for the DCR register ✨

---

🌸 SYNOPSIS 🌸

the signature, verbatim, because code does not do vibes-only:

void parport_ip32_write_control (struct parport *p , unsigned char c );

it returns void, so there’s no return value to obsess over. periodt. 💅

---

🫶 ARGUMENTS 🫶

two little besties walk in:

• p — pointer to struct parport
• c — new value to write

---

💖 DESCRIPTION 💖

okay so here’s the mask moment: the value you pass in as c gets masked, and the mask is set up so the only values that change are DCR_STROBE, DCR_AUTOFD, DCR_nINIT, and DCR_SELECT. that’s the whole plot, bestie. 🎀
