NAME
     X Color Management DDC/CI communication API's -

   Enumerations
     enum  XCM_DDC_ERROR_e  { XCM_DDC_OK, XCM_DDC_NO_FILE, XCM_DDC_PREPARE_FAIL,
	 XCM_DDC_EDID_READ_FAIL, XCM_DDC_WRONG_EDID }
	 errors specific to XcmDDC

   Functions
     XCM_DDC_ERROR_e XcmDDClist (char ***list, int *count)
	 obtain all monitors i2c device names
     XCM_DDC_ERROR_e XcmDDCgetEDID (const char *device_name, char **data, size_t
	 *size)
	 obtain all monitors i2c device names
     const char * XcmDDCErrorToString (XCM_DDC_ERROR_e error)
	 convert enum into a meaningful text string

Detailed Description
     The purpose of the API is to establish client  side  communication  with  a
     monitor  device. This can be used to update EEDID data and get MCCS proper-
     ties. The former is supported by this library.

     XcmDDClist() returns a list of monitor i2c  device  names.  XcmDDCgetEDID()
     can be used to fetch EEDID from a device name.
