π MAX_INBOUND_BUFFER_SIZE(9) π
okay bestie, welcome to the Kernel API Manual β this one's a macro page, section 9, kernel-ville, and it's honestly short and sweet. let's get into it β¨
πΈ NAME πΈ
MAX_INBOUND_BUFFER_SIZE β literally just the maximum size of the inbound buffer. that's it. that's the whole name. iconic minimalism π
π¦ SYNOPSIS π¦
MAX_INBOUND_BUFFER_SIZE
no args, no parentheses, no drama β it's a macro, she just is π
β¨ DESCRIPTION β¨
okay so here's the tea π β the size of that inbound buffer is not a fixed vibe. it depends on what the user's requests actually ask for, specifically the number of IB and OB arguments. like, the buffer size is giving "it depends on your order" energy, yk?
so if some invocation needs a size that's larger than MAX_INBOUND_BUFFER_SIZE... yeah, no cap, that's your sign π«Ά. the user should lowkey consider using another form of shared memory with QTEE. that's the whole move. periodt.
π fr fr, this is the ceiling β if you're bumping up against it, switch strategies, don't try to make it fit.
