# bio\_copy\_data(9)

copy contents of data buffers from one chain of bios to another

## NAME

bio\_copy\_data - copy contents of data buffers from one chain of bios to another

## SYNOPSIS

**void bio\_copy\_data(struct bio \*** *dst***, struct bio \*** *src***);**

## ARGUMENTS

*dst*

destination bio list

*src*

source bio list

## DESCRIPTION

If *src* and *dst* are single bios, bi\_next must be NULL - otherwise, treats *src* and *dst* as linked lists of bios.

Stops when it reaches the end of either *src* or *dst* - that is, copies min(src-\>bi\_size, dst-\>bi\_size) bytes (or the equivalent for lists of bios).
