build_interp_argv(9)

💖 NAME 💖

okay so bestie, welcome to build_interp_argv(9) — yes, that's the name, and this whole page is living in the Kernel API Manual. It's literally the function that splices the interpreter invocation into the argv. slay. ✨

✨ SYNOPSIS ✨

int build_interp_argv (struct linux_binprm *bprm , const char
       *interpreter , unsigned long flags );

🎀 ARGUMENTS 🎀

• bprm — the binary that is being executed. main character binary energy, honestly.
• interpreter — the interpreter selected for this exec. the chosen one 💅
• flags — invocation flags in effect for this exec. all the flag vibes, gathered for this exact exec.

🦋 DESCRIPTION 🦋

okay so here's the tea: the interpreter becomes argv[0] and the binary becomes its last argument, with an optional staged argument in between. cute, right? the caller's argv[0] is dropped unless 'P' keeps it. that's the whole vibe — no cap. 💖

🌸 RETURN 🌸

0 on success, and a negative error code on failure. periodt. 💅
