.AC "Request Processing" 2
.LP
Workstation regeneration and requests which process output commands
are not guaranteed to be atomic with respect to concurrent rendering
to the same destination drawable. However atomicity of execution is
guaranteed for each individual output command primitive, excluding
Execute Structure, GSE, GDP 3D, and GDP 2D. Also, requests and output
commands will be executed in sequential order for a given connection.
.AC "Protocol Format" 2
.LP
.AC "Request Format" 3
.LP
Requests are listed in section 2.8 and in section 4 through the end of the
document. Output Commands are described in section 3.
.AC "Reply Format" 3
.LP
Replies are listed after the request.
.AC "Error Format" 3
.LP
See section 2.5.7 for the encoding of particular errors.
.AC "Event Format" 3
.LP
See section 2.6 for the encoding of events.
.AC "Syntax" 2
.LP
As far as possible, this document uses the layout and syntactic conventions used
in the X encoding document. In particular, note that all numbers are decimal,
unless prefixed by #x, in which case they are hexadecimal. Also note that, for
entities of a variable size, E, the notation pad(E) indicates the number of
bytes required to pad the entity to a multiple of 4 bytes.
.LP
There are some unavoidable differences from the X encoding document
conventions, however, because of the many variable sized entities and entities
with optional data in PEX.
.AC "Naming Conventions" 2
.LP
The names of the fields in requests, replies and lists of values match the
names used in the \fIPEX Protocol Specification\fP.
.AC "Common Types" 2
.LP
The types listed in this section are some of the types mentioned in
the PEX protocol. Generally, derivative types (e.g. ENUM_TYPE_INDEX)
are replaced by the primitive or primitives of which they are composed
(e.g. INT16). Only when this is impractical is the derivative type
used; generally this is when the type is of variable length or a
list of compound types is used.
.AC "LISTofFOO" 3
.LP
In this document, a LISTofFOO is a counted list of elements of type FOO,
the count field preceding it in the request or reply.
.LP
In cases where the number of items in the list is easily computed from the
length of the list, the number of items may not be supplied. (See, for
example, the \fBPolyline3D\fP output command.) The goal is to reduce the
burden on the client. Such cases are indicated in the encoding document.
.LP
There is also no count provided for a list that has an associated
item_mask.
.LP
Unless otherwise marked, a LISTofLISTofFOO is implemented as follows:
somewhere in the request or reply there is a number of lists field (perhaps
several if there are multiple lists of lists). Each LIST is preceded by
a CARD32 count field.
.LP
So the overall format is:
.LP
.Ds 0
.TA .2i 1i 2i 3.1i
.ta .2i 1i 2i 3.1i
.R
4 CARD32 number of lists
. . . (potentially other things here)
4 CARD32 number of items in first list
n FOO first item of first list
n FOO second item of first list
. . .
n FOO last item of first list
4 CARD32 number of items in second list
n FOO first item of second list
. . .
.De
.LP
In only one place in the PEX protocol is a LISTofLISTofLISTofFOO
required, in the \fBSetOfFillAreaSets\fP output command. In this case,
the number of lists is a CARD16. Other counts within the list are
CARD16.
.LP
The format of this is:
.LP
.Ds 0
.TA .2i 1i 2i 3.1i
.ta .2i 1i 2i 3.1i
.R
2 CARD16 number of lists of lists
. . . (potentially other things here)
2 CARD16 number of lists in first list of list
2 CARD16 number of items in first list
n FOO first item of first list
n FOO second item of first list
. . .
n FOO last item of first list
2 CARD16 number of items in second list
n FOO first item of second list
. . .
2 CARD16 number of lists in second list of list

.AC "BITMASK and LISTofVALUE" 3
.LP
Because the values in a value list are of variable size, a list of values
can only be interpreted serially; there is no way to find the Nth element
without examining the N-1 previous elements.
.LP
Elements have all been padded to a multiple of 4 bytes. If values appear
which could be encoded in less space, it is assumed that they will be
placed in the least significant bits of the word. (Byte-swapping may occur
between the client and the server.)
.AC "Floating Point Format - FLOAT" 3
.LP
A FLOAT is a floating point quantity in one of the server supported formats. If
the client wishes to communicate with the server in other than the server's
native floating point format, the server must perform the necessary
conversions. The format word of a request tells the server what format the
client wishes to use.
.LP
Depending on the floating point format, the size of a FLOAT may be 4 or
8 bytes. Floating point values passed to the server may be in any one
of the registered floating point formats:
.TA .2i .6i 1.6i 3.1i
.ta .2i .6i 1.6i 3.1i
.nf
1 IEEE_754_32 4 bytes
2 DEC_F_Floating 4 bytes
3 IEEE_754_64 8 bytes
4 DEC_D_Floating 8 bytes
.fi
Equations are provided for computing the length of the requests that
contain floating point values, however these equations assume that one of the
four registered floating point formats is being used.
In all of these equations, the name \fIfp\fP refers to the size in bytes
of a FLOAT in the floating point format indicated in the format word of
the request.
.AC "Colors" 3
.LP
Colors passed to the server may be of any one of the registered
color types:
.TA .2i 1i 2i 3.1i
.ta .2i 1i 2i 3.1i
.nf
0 Indexed
1 RGBFloat
2 CIEFloat
3 HSVFloat
4 HLSFloat
5 RGBInt8
6 RGBInt16
.fi
Equations are provided for computing the length of the requests that
contain colors, however these equations assume that one of the seven
registered color types and one of the four registered floating point
formats is being used.
.AC "Element Types" 3
.LP
.AC "Types" 3
.LP
Some PEX requests and replies contain matrices. These are denoted in this
document as FLOAT[4][4] or FLOAT[3][3]. The elements of
the matrices are sent over the wire in a row-wise manner. That is, the element
of a 4\(mu4 transformation matrix that indicates the
translation in the X direction is the fourth element sent.
.LP
The following compound types appear in the rest of the encoding document.
For a complete list of types refer to the protocol document.
If a variable is given which computes the length of a compound type (e.g.,
the equation for d in OPT_DATA), that variable may be used later to express
the length of a request or reply (e.g. the \fBTriangleStrip\fP output
command).

Some resources have attributes that contain IDs of other resources. It
is possible for the referenced resource to be freed while the referencing
resource remains in use. Attempts to query attributes containing the resource
ID of a resource that has already been freed will return the value
\fIAlreadyFreed\fP (whose value equals one).

The following components may appear in the requests \fBPEXCreatePipelineContext\fP
and \fBPEXChangePipelineContext\fP; they may also appear in replies to
\fBPEXGetPipelineContext\fP. Because the components are not of a fixed size
(as they are in X11), the list must be parsed serially to know where one
component ends and the next begins. A bitmap mask of three CARD32s specifies
which components are to be found in a list. Proceding from the least
significant bit of the first CARD32 through to the last used bit of the
third CARD32, if the bit is set, the next item in the list is of the
specified type.

\fINote:\fR The asf_enables field is only used for the
\fBPEXCreatePipelineContext\fP and \fBPEXChangePipelineContext\fP requests.
For those requests, if the asf_enables bit for a particular asf is set, the
asf value is taken from the corresponding bit in the asfs field. For the
\fBPEXGetPipelineContext\fP reply, asf_enables is present, but has no meaning
and must have all defined asf bits set.

Note that entries in the list are all padded to a multiple of 4 bytes.
If values appear which could be encoded in less space, it is assumed
that they will be placed in the least significant bits of the word.
If a component has sub-fields, the sizes, types and interpretations of the
sub-fields are on subsequent lines.

The following components may appear in the reply of \fBPEXGetWKSInfo\fP.
Because the components are not of a fixed size
(as they are in X11), the list must be parsed serially to know where one
component ends and the next begins. A bitmap mask of two CARD32s in the
request specifies which components are to be found in the reply.
Proceding from the least
significant bit of the first CARD32 through to the last used bit of the
second CARD32, if the bit is set, the next item in the list is of the
specified type.
