💖 tcw_get_data(9) 💖

okay bestie, welcome to the Kernel API Manual — this is the page for tcw_get_data, and it's literally the glow-up guide for grabbing the data pointer out of a tcw. no cap. 🫶

🌸 NAME 🌸

tcw_get_data — return pointer to input/output data associated with tcw

✨ SYNOPSIS ✨

void * tcw_get_data (struct tcw *tcw );

🎀 ARGUMENTS 🎀

• tcw — pointer to the tcw. that's the whole vibe. 💅

🦋 DESCRIPTION 🦋

okay so here's the tea: this function returns the input or output data address specified in the tcw, depending on whether the r-bit or the w-bit is set. lowkey simple, highkey iconic. ✨

if neither bit is set? it returns NULL. that's it. no drama, no extra steps, just NULL. 💀
