di_info_destroy() ¶

void di_info_destroy(​struct di_info *info);

Destroy a display device information structure.

di_info_get_edid() ¶

const struct di_edid *di_info_get_edid(​const struct di_info *info);

Returns the EDID the display device information was constructed with.

The returned struct di_edid can be used to query low-level EDID information, see <libdisplay-info/edid.h>. Users should prefer the high-level API if possible.

NULL is returned if the struct di_info doesn't contain an EDID. The returned struct di_edid is valid until di_info_destroy().

di_info_get_failure_msg() ¶

const char *di_info_get_failure_msg(​const struct di_info *info);

Get the failure messages for this blob.

NULL is returned if the blob conforms to the relevant specifications.

di_info_get_make() ¶

char *di_info_get_make(​const struct di_info *info);

Get the make of the display device.

This is the manufacturer name, either company name or PNP ID. This string is informational and not meant to be used in programmatic decisions, configuration keys, etc.

The string is in UTF-8 and may contain any characters except ASCII control codes.

The caller is responsible for free'ing the returned string. NULL is returned if the information is not available.

di_info_get_model() ¶

char *di_info_get_model(​const struct di_info *info);

Get the model of the display device.

This is the product name/model string or product number. This string is informational and not meant to be used in programmatic decisions, configuration keys, etc.

The string is in UTF-8 and may contain any characters except ASCII control codes.

The caller is responsible for free'ing the returned string. NULL is returned if the information is not available.

di_info_get_serial() ¶

char *di_info_get_serial(​const struct di_info *info);

Get the serial of the display device.

This is the product serial string or the serial number. This string is informational and not meant to be used in programmatic decisions, configuration keys, etc.

The string is in UTF-8 and may contain any characters except ASCII control codes.

The caller is responsible for free'ing the returned string. NULL is returned if the information is not available.

di_info_parse_edid() ¶

struct di_info *di_info_parse_edid(​const void *data, size_t size);

Parse an EDID blob.

Callers do not need to keep the provided data pointer valid after calling this function. Callers should destroy the returned pointer via di_info_destroy().
