Detailed Description

I2C adapter class.


Function Documentation

char* i2c_adapter_compute_udi HalDevice d,
int  append_num
[static]
 

This function will compute the device uid based on other properties of the device.

For I2C adapters it is the adapter number.

Parameters:
d HalDevice object
append_num Number to append to name if not -1
Returns:
New unique device id; only good until the next invocation of this function

void visit_class_device_i2c_adapter const char *  path,
struct sysfs_class_device *  class_device
 

Visitor function for I2C adapter.

This function parses the attributes present and creates a new HAL device based on this information.

Parameters:
path Sysfs-path for device
device libsysfs object for device

Todo:
: see if we already got this device

Callback when the parent is found or if there is no parent..

This is where we get added to the GDL..

Parameters:
parent Async Return value from the find call
data1 User data
data2 User data
