nfp_cpp_explicit_do(9)

💅 nfp_cpp_explicit_do(9) 💅

okay so welcome to the Kernel API Manual, bestie! this is the page for nfp_cpp_explicit_do(9), and it's literally about executing a transaction and then waiting for it to complete. main character energy: does the thing, waits for the thing. periodt. ✨

🌸 NAME 🌸

nfp_cpp_explicit_do — Execute a transaction, and wait for it to complete. no cap, she's patient. 🫶

🎀 SYNOPSIS 🎀

int nfp_cpp_explicit_do (struct nfp_cpp_explicit *expl , u64 address );

🦋 ARGUMENTS 🦋

• expl — NFP CPP Explicit handle. that's your lil' explicit-transaction handle, bestie 💖
• address — Address to send in the explicit transaction. yes, the actual address, not a vibe check.

🔥 DESCRIPTION 🔥

Okay so here's the tea: if this function is called before the configuration registers are set, it will return -1, with an errno of EINVAL.

⚠️ so that's the warning, bestie: config registers not set yet = -1 and EINVAL. don't act surprised 😭

👑 RETURN 👑

0, or -ERRNO. that's it. iconic, concise, no notes. slay. 💅
