# usb\_ep\_align\_maybe(9)

returns len aligned to ep's maxpacketsize if gadget requires quirk\_ep\_out\_aligned\_size, otherwise returns len.

## NAME

usb\_ep\_align\_maybe - returns *len* aligned to ep's maxpacketsize if gadget requires quirk\_ep\_out\_aligned\_size, otherwise returns len.

## SYNOPSIS

**size\_t usb\_ep\_align\_maybe(struct usb\_gadget \*** *g***, struct usb\_ep \*** *ep***, size\_t** *len***);**

## ARGUMENTS

*g*

controller to check for quirk

*ep*

the endpoint whose maxpacketsize is used to align *len*

*len*

buffer size's length to align to *ep*'s maxpacketsize

## DESCRIPTION

This helper is used in case it's required for any reason to check and maybe align buffer's size to an ep's maxpacketsize.
