# put\_unaligned(9)

put value to a possibly mis-aligned location

## NAME

put\_unaligned - put value to a possibly mis-aligned location

## SYNOPSIS

**put\_unaligned(***val***,** *ptr***);**

## ARGUMENTS

*val*

value to place

*ptr*

pointer to location

## DESCRIPTION

This macro should be used for placing values larger in size than single bytes at locations that are expected to be improperly aligned, e.g. writing a u16 value to a location not u16-aligned.

Note that unaligned accesses can be very expensive on some architectures.
