is_ep_periodic(9)
β¨ is_ep_periodic β¨
okay so bestie, let me tell you about is_ep_periodic from the Kernel API Manual (section 9, the big-kid kernel developer section, iykyk π
).
πΈ NAME πΈ
is_ep_periodic β it literally returns true if the endpoint is in periodic mode. that's it. that's the whole vibe check π
π¦ SYNOPSIS π¦
int is_ep_periodic (struct dwc2_hsotg_ep *hs_ep );
π ARGUMENTS π
hs_epβ the endpoint you're querying. like, the one you're asking about. give it a little look π
β¨ DESCRIPTION β¨
so basically this function returns true if the endpoint is in periodic mode β meaning it's being used for an Interrupt or ISO transfer. iconic behavior honestly π₯
