The purpouse of this API is to obtain basic and displayable device identi- fication strings and colorimetric informations contained in the EDID data block sent by monitors. The user has to pass in a valid EDID block. This can be obtained per a root window X atom or a XRandR output property and is not part of this API. The data block is passed to XcmEdidParse(). This function generates a list of key value pairs, with some first rough interpretation. The key/values are useable for data bases, ICC profile generation or device identification. The returned XcmEdidKeyValue_s list elements can be individually read and worked with. Please look as well on the XcmEdidPrintString() function and examples/edid-parse/ as a small example on how to use the API. The XcmEdid- PrintOpenIccJSON() will pull out a JSON data structure. XcmEdidFree() re- leases allocated list memory.
