Copy Code
        const AT_DCM_VR vr_mode,
        LPCHAR lpVRstring, 
        LPWORD lpwLength, 
        LPWORD lpwRestriction, 
        LPBOOL lpCheck_form, 
        LPBOOL lpIsString


Name Type Description
vr_mode const AT_DCM_VR Set this to the type of VR (or data type) you would like information on. See enumIGMedVR for possible VR values.
lpVRstring LPCHAR A far pointer that returns the text representation of VR in 3 characters.
lpwLength LPWORD A far pointer that returns the size of the VR.
lpwRestriction LPWORD A far pointer that returns any restriction flags. These will be returned as constants that are defined in enumIGMedVRRestriction and begin with MED_DCM_LEN_.
