Neither of those files should be +edited directly. Changing the atoms in this file, or even the order in +which they occur, is equivalent to forcing a new (minor) version number +on the server. Take care. + +The format of the file is that each built in atom starts in column 1 +with no text, other than spaces and tabs, on that line other than a +mandatory trailing "@" at the end of the line. For each atom (Foo) +below the defines will be of the form + #define XA_Foo <n> +and the string value of the atom will be "Foo". + +The comment lines in this file are not guaranteed to be accurate. To see the +current truth, look at the Xlib documentation as well as the protocol spec. + +Atoms occur in five distinct name spaces within the protocol. Any particular +atom may or may not have some client interpretation within each of the name +spaces. For each of the built in atoms, the intended semantics and the space +within which it is defined is indicated. + +Those name spaces are + Property names + Property types + Selections + Font properties + Type of a ClientMessage event (none built into server) + +For the font properties mentioned here, see the spec for more information. + + -- Selections -- + +PRIMARY @ + Selection. +SECONDARY @ + Selection. + + -- Property types and names -- + +ARC @ + Property type: + x, y: INT16 + width, height: CARD16, + angle1, angle2: INT16 +ATOM @ + Property type: + atom: ATOM +BITMAP @ + Property type: + bitmap: PIXMAP + This is asserted to be of depth 1. +CARDINAL @ + Property type: + card: CARD32 or CARD16 or CARD8 + the datum size is dependent on the property format +COLORMAP @ + Property type: + colormap: COLORMAP +CURSOR @ + Property type: + cursor: CURSOR +CUT_BUFFER0 @ +CUT_BUFFER1 @ +CUT_BUFFER2 @ +CUT_BUFFER3 @ +CUT_BUFFER4 @ +CUT_BUFFER5 @ +CUT_BUFFER6 @ +CUT_BUFFER7 @ + Property name: (type: STRING) + Used to implement cut buffer ring, in particular Andrew uses + this mechanism.

Each color + coefficient ranges from 0 to its max, inclusive. For example, + a common colormap allocation is 3/3/2: 3 planes for red, 3 + planes for green, and 2 planes for blue. Such a colormap would + have red_max == 7, green_max = 7, and blue_max = 3. An alternate + allocation that uses only 216 colors is red_max = 5, green_max = + 5, and blue_max = 5. + + The fields `red_mult', `green_mult', and `blue_mult' give the + scale factors used to compose a full pixel value. (See next + paragraph.) For a 3/3/2 allocation red_mult might be 32, + green_mult might be 4, and blue_mult might be 1. For a + 6-colors-each allocation, red_mult might be 36, green_mult might + be 6, and blue_mult might be 1. + + The field `base_pixel' gives the base pixel value used to + compose a full pixel value. Normally base_pixel is obtained + from a call to XAllocColorPlanes(). Given integer red, green, + and blue coefficients in their appropriate ranges, one can + compute a corresponding pixel value with the expression: + + r * red_mult + g * green_mult + b * blue_mult + base_pixel + + For gray-scale colormaps, only the colormap, red_max, red_mult, + and base_pixel fields are defined; the other fields are + ignored.
