(sensors_chip_name name, int *nr1,int *nr2);
int
sensors_init(FILE *input);
(Re)load the configuration file and the detected chips list.
If this returns a value unequal to zero, you are in trouble;
you can not assume anything will be initialized
properly.
void
sensors_cleanup(void);
Clean-up function: You can’t access anything after
this, until the next sensors_init() call!
int
sensors_parse_chip_name(const char *orig_name,
sensors_chip_name *res);
Parse a chip name to the internal representation. Return 0
on succes, <0 on error.
int
sensors_match_chip(sensors_chip_name chip1,
sensors_chip_name chip2);
Compare two chips name descriptions, to see whether they
could match. Return 0 if it does not match, return 1 if it
does match.
int
sensors_chip_name_has_wildcards
(sensors_chip_name chip);
Check whether the chip name is an ’absolute’
name, which can only match one chip, or whether it has
wildcards. Returns 0 if it is absolute, 1 if there are
wildcards.
const char
*sensors_get_adapter_name(int bus_nr);
This function returns the adapter name of a bus number, as
used within the sensors_chip_name structure. If it could not
be found, it returns NULL.
const char
*sensors_get_algorithm_name(int bus_nr);
This function used to return the algorithm name of a bus
number. It is now deprecated and returns an arbitrary
string. It will be dropped in a later version of the library
so you should stop using it.
int
sensors_get_label(sensors_chip_name name, int feature,
char **result);
Look up the label which belongs to this chip. Note that chip
should not contain wildcard values! *result is newly
allocated (free it yourself). This function will return 0 on
success, and <0 on failure.
int
sensors_get_feature(sensors_chip_name name,
int feature, double *result);
Read the value of a feature of a certain chip. Note that
chip should not contain wildcard values! This function will
return 0 on success, and <0 on failure.
int
sensors_set_feature(sensors_chip_name name,
int feature, double value);
Set the value of a feature of a certain chip. Note that chip
should not contain wildcard values! This function will
return 0 on success, and <0 on failure.
int
sensors_do_chip_sets(sensors_chip_name name);
Execute all set statements for this particular chip. The
chip may contain wildcards! This function will return 0 on
success, and <0 on failure.
int
sensors_do_all_sets(void);
Execute all set statements for all detected chips. This is
the same as calling sensors_do_chip_sets with an all
wildcards chip name
const
sensors_chip_name *sensors_get_detected_chips
(int *nr);
This function returns all detected chips, one by one. To
start at the beginning of the list, use 0 for nr; NULL is
returned if we are at the end of the list. Do not try to
change these chip names, as they point to internal
structures! Do not use nr for anything else.
This structure
is used when you want to get all features of a specific
chip.
typedef struct sensors_feature_data {
int number;
const char *name;
int mapping;
int unused;
int mode;
} sensors_feature_data;
The mode field can be one of:
SENSORS_MODE_NO_RW, SENSORS_MODE_R, SENSORS_MODE_W or
SENSORS_MODE_RW.
const
sensors_feature_data *sensors_get_all_features
(sensors_chip_name name, int *nr1,int *nr2);
This returns all features of a specific chip. They are
returned in bunches: everything with the same mapping is
returned just after each other, with the master feature in
front (that feature does not map to itself, but has
SENSORS_NO_MAPPING as mapping field). nr1 and nr2 are two
internally used variables. Set both to zero to start again
at the begin of the list. If no more features are found NULL
is returned. Do not try to change the returned structure;
you will corrupt internal data structures.
