DocsTable of Contents
All numbers are in decimal, unless prefixed with #x, in which case they are in hexadecimal (base 16).
The general syntax used to describe requests, replies, errors, events, and compound types is:
NameofThing
encode-form
...
encode-form
Each encode-form describes a single component.
For components described in the protocol as:
name: TYPE
the encode-form is:
N TYPE name
N is the number of bytes occupied in the data stream, and TYPE is the interpretation of those bytes. For example,
depth: CARD8
becomes:
1 CARD8 depth
For components with a static numeric value the encode-form is:
N value name
The value is always interpreted as an N-byte unsigned integer. For example, the first two bytes of a Window error are always zero (indicating an error in general) and three (indicating the Window error in particular):
1 0 Error
1 3 code
For components described in the protocol as:
name: { Name1,..., NameI}
the encode-form is:
N name
value1 Name1
...
valueI NameI
The value is always interpreted as an N-byte unsigned integer. Note that the size of N is sometimes larger than that strictly required to encode the values. For example:
class: { InputOutput, InputOnly, CopyFromParent }
becomes:
2 class
0 CopyFromParent
1 InputOutput
2 InputOnly
For components described in the protocol as:
NAME: TYPE or Alternative1 ...or AlternativeI
the encode-form is:
N TYPE NAME
value1 Alternative1
...
valueI AlternativeI
The alternative values are guaranteed not to conflict with the encoding of TYPE. For example:
destination: WINDOW or PointerWindow or InputFocus
becomes:
4 WINDOW destination
0 PointerWindow
1 InputFocus
For components described in the protocol as:
value-mask: BITMASK
the encode-form is:
N BITMASK value-mask
mask1 mask-name1
...
maskI mask-nameI
The individual bits in the mask are specified and named, and N is 2 or 4. The most-significant bit in a BITMASK is reserved for use in defining chained (multiword) bitmasks, as extensions augment existing core requests. The precise interpretation of this bit is not yet defined here, although a probable mechanism is that a 1-bit indicates that another N bytes of bitmask follows, with bits within the overall mask still interpreted from least-significant to most-significant with an N-byte unit, with N-byte units interpreted in stream order, and with the overall mask being byte-swapped in individual N-byte units.
For LISTofVALUE encodings, the request is followed by a section of the form:
VALUEs
encode-form
...
encode-form
listing an encode-form for each VALUE. The NAME in each encode-form keys to the corresponding BITMASK bit. The encoding of a VALUE always occupies four bytes, but the number of bytes specified in the encoding-form indicates how many of the least-significant bytes are actually used; the remaining bytes are unused and their values do not matter.
In various cases, the number of bytes occupied by a component will be specified by a lowercase single-letter variable name instead of a specific numeric value, and often some other component will have its value specified as a simple numeric expression involving these variables. Components specified with such expressions are always interpreted as unsigned integers. The scope of such variables is always just the enclosing request, reply, error, event, or compound type structure. For example:
2 3+n request length
4n LISTofPOINT points
For unused bytes (the values of the bytes are undefined and do no matter), the encode-form is:
N unused
If the number of unused bytes is variable, the encode-form typically is:
p unused, p=pad(E)
where E is some expression, and pad(E) is the number of bytes needed to round E up to a multiple of four.
pad(E) = (4 - (E mod 4)) mod 4
LISTofFOO | In this document the LISTof notation strictly means some number of repetitions of the FOO encoding; the actual length of the list is encoded elsewhere. |
SETofFOO | A set is always represented by a bitmask, with a 1-bit indicating presence in the set. |

For TCP connections, displays on a given host are numbered starting from 0, and the server for display N listens and accepts connections on port 6000 + N. For DECnet connections, displays on a given host are numbered starting from 0, and the server for display N listens and accepts connections on the object name obtained by concatenating "X$X" with the decimal representation of N, for example, X$X0 and X$X1.
