/* These funcion reads or writes a 'real' value (encoded by the combination

of an integer and a magnitude, the last is the power of ten the value

should be divided with) to a /proc/sys directory. To use these functions,
|
|
you must (before registering the ctl_table) set the extra2 field to the
|
|
client, and the extra1 field to a function of the form:
|
|
void func(struct i2c_client *client, int operation, int ctl_name,

|
int *nrels_mag, long *results)
|
|
This last function can be called for three values of operation. If
|
|
operation equals SENSORS_PROC_REAL_INFO, the magnitude should be returned
|
|
in nrels_mag. If operation equals SENSORS_PROC_REAL_READ, values should
|
|
be read into results. nrels_mag should return the number of elements
|
|
read; the maximum number is put in it on entry. Finally, if operation
|
|
equals SENSORS_PROC_REAL_WRITE, the values in results should be
|
|
written to the chip. nrels_mag contains on entry the number of elements
|
|
found.
|
|
In all cases, client points to the client we wish to interact with,
|
|
and ctl_name is the SYSCTL id of the file we are accessing. */
