IIO_TRIGGERED_BUFFER(9) Industrial I/O core IIO_TRIGGERED_BUFFER(9)

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.
