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
       properties. 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.
