trace_print_seq(9)

🌸 NAME 🌸

okay so trace_print_seq is the function we're talking about, and this page is from the Kernel API Manual, bestie 💖. Its whole job: move the contents of trace_seq into a seq_file. That's it. That's the vibe. main character energy for a tiny little function, ngl ✨.

🦋 SYNOPSIS 🦋

int trace_print_seq (struct seq_file *m , struct trace_seq *s );

🎀 ARGUMENTS 🎀

• m — the seq_file descriptor that is the destination. where the stuff is going 🫶
• s — the trace_seq descriptor that is the source. where the stuff is coming from ✨

💅 DESCRIPTION 💅

Returns 0 on success and non zero on error. periodt 👑

If it succeeds to write to the seq_file it will reset the trace_seq. If it doesn't succeed? Then it does not modify the trace_seq — specifically to let the caller try again. no cap, that retry-friendliness is lowkey iconic 😭.
