</para>
<para>
<!-- .LP -->
All numbers are in decimal,
unless prefixed with #x, in which case they are in hexadecimal (base 16).
</para>
<para>
<!-- .LP -->
The general syntax used to describe requests, replies, errors, events, and
compound types is:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<function>NameofThing</function>
encode-form
...
encode-form
</literallayout>
Each encode-form describes a single component.
</para>
<para>
<!-- .LP -->
For components described in the protocol as:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
name: TYPE
</literallayout>
the encode-form is:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2.5i -->
<!-- .ta 1i 1.5i 2.5i -->
N TYPE name
</literallayout>
N is the number of bytes occupied in the data stream,
and TYPE is the interpretation of those bytes.
For example,
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i -->
<!-- .ta 1i 1.5i -->
depth: CARD8
</literallayout>
becomes:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2.5i -->
<!-- .ta 1i 1.5i 2.5i -->
1 CARD8 depth
</literallayout>
For components with a static numeric value the encode-form is:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2.5i -->
<!-- .ta 1i 1.5i 2.5i -->
N value name
</literallayout>
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):
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2.5i -->
<!-- .ta 1i 1.5i 2.5i -->
1 0 Error
1 3 code
</literallayout>
For components described in the protocol as:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
name: <function>{Name1, ..., NameI}</function>
</literallayout>
</para>
<para>
<!-- .LP -->
the encode-form is:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2.5i -->
<!-- .ta 1i 1.5i 2.5i -->
N name
value1 Name1
...
valueI NameI
</literallayout>
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:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
class: <function>{InputOutput, InputOnly, CopyFromParent}</function>
</literallayout>
</para>
<para>
<!-- .LP -->
becomes:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2.5i 3i -->
<!-- .ta 1i 1.5i 2.5i 3i -->
2 class
0 CopyFromParent
1 InputOutput
2 InputOnly
</literallayout>
For components described in the protocol as:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
NAME: TYPE or <function>Alternative1 ... or AlternativeI</function>
</literallayout>
</para>
<para>
<!-- .LP -->
the encode-form is:

<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2i 2.5i 3i -->
<!-- .ta 1i 1.5i 2i 2.5i 3i -->
N TYPE NAME
value1 Alternative1
...
valueI AlternativeI
</literallayout>
The alternative values are guaranteed not to conflict with the encoding
of TYPE.
For example:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
destination: WINDOW or <function>PointerWindow</function> or <function>InputFocus</function>
</literallayout>
</para>

</literallayout>
For components described in the protocol as:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i -->
<!-- .ta 1i 1.5i -->
value-mask: BITMASK
</literallayout>
the encode-form is:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2i 2.5i -->
<!-- .ta 1i 1.5i 2i 2.5i -->
N BITMASK value-mask
mask1 mask-name1
...
maskI mask-nameI
</literallayout>
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.
</para>
<para>
<!-- .LP -->
For LISTofVALUE encodings, the request is followed by a section of the form:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i -->
<!-- .ta 1i 1.5i -->
VALUEs
encode-form
...
encode-form
</literallayout>
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.
</para>
<para>
<!-- .LP -->
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:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2i 2.5i -->
<!-- .ta 1i 1.5i 2i 2.5i -->
2 3+n request length
4n LISTofPOINT points
</literallayout>
For unused bytes (the values of the bytes are undefined and do not matter),
the encode-form is:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2i 2.5i -->
<!-- .ta 1i 1.5i 2i 2.5i -->
N unused
</literallayout>
If the number of unused bytes is variable, the encode-form typically is:
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2i 2.5i -->
<!-- .ta 1i 1.5i 2i 2.5i -->
p unused, p=pad(E)
</literallayout>
where E is some expression,
and pad(E) is the number of bytes needed to round E up to a multiple of four.
</para>
<para>
<!-- .LP -->
<literallayout class="monospaced">
<!-- .TA 1i 1.5i 2i 2.5i -->
<!-- .ta 1i 1.5i 2i 2.5i -->
pad(E) = (4 - (E mod 4)) mod 4
