pch_udc_ep_set_trfr_type(9)
π pch_udc_ep_set_trfr_type(9) β from the Kernel API Manual, bestie β¨
okay so picture this: you're deep in the kernel API manual, section 9, and you've got this one function, pch_udc_ep_set_trfr_type, that just... sets the transfer type of an endpoint. that's it. that's the whole vibe. it's giving quiet luxury, honestly. π
β¨ NAME β¨
pch_udc_ep_set_trfr_type β literally just sets the transfer type of an endpoint π¦ no drama, no plot twist, it does exactly what it says on the tin.
πΈ SYNOPSIS πΈ
void pch_udc_ep_set_trfr_type (struct pch_udc_ep *ep , u8 type );
it returns void, so like... it doesn't hand you anything back. it does the thing and it's done. main character energy, no receipts. π
π ARGUMENTS π
get comfy, there's two of them:
epβ a reference to a structure of typepch_udc_ep_regs. yes, the manpage sayspch_udc_ep_regsright there next to thepch_udc_epin the synopsis, and we are not gonna gaslight ourselves about it β that's literally what it says, so that's what we're telling you. π«Άtypeβ the type of endpoint. that's the whole description. the type. of the endpoint. slay, honestly. π

okay bestie this is the part where the manpage pops off β it's a whole friend group, a whole group chat, an entire roster of kernel functions and structs that are all linked up. every single one, no cap, in order:

like... the way this list just keeps going?? iconic. iykyk. π
and that's the page, bestie π«Ά this lil cutie lives under ./drivers/usb/gadget/udc, it's dated October 2026, and yes the header and footer both say pch_udc_ep_set_trfr_type(9) because it's that girl and she's not afraid to say her own name twice. mwah πβ¨
