# iio\_triggered\_buffer\_setup(9)

Setup triggered buffer and pollfunc

## NAME

iio\_triggered\_buffer\_setup - Setup triggered buffer and pollfunc

## SYNOPSIS

**int iio\_triggered\_buffer\_setup(struct iio\_dev \*** *indio\_dev***, irqreturn\_t (\****h***) (int irq, void \*p), irqreturn\_t (\****thread***) (int irq, void \*p), const struct iio\_buffer\_setup\_ops \*** *setup\_ops***);**

## ARGUMENTS

*indio\_dev*

IIO device structure

*h*

Function which will be used as pollfunc top half

*thread*

Function which will be used as pollfunc bottom half

*setup\_ops*

Buffer setup functions to use for this device. If NULL the default setup functions for triggered buffers will be used.

## DESCRIPTION

This function combines some common tasks which will normally be performed when setting up a triggered buffer. It will allocate the buffer and the pollfunc.

Before calling this function the indio\_dev structure should already be completely initialized, but not yet registered. In practice this means that this function should be called right before **iio\_device\_register**.

To free the resources allocated by this function call **iio\_triggered\_buffer\_cleanup**.
