74 The various attributes for param and glx have the meanings listed below.
75 When adding new functions, please annote them correctly. In most cases this
76 will just mean adding a '<glx ignore="true"/>' tag.
77
78 param:
79 name - name of the parameter
80 type - fully qualified type (e.g., with "const", etc.)
81 count - for counted arrays (e.g., the 'lists' parameter to glCallLists),
82 the parameter or literal that represents the count. For functions
83 like glVertex3fv it will be a litteral, for others it will be one of
84 the parameters.
85 counter - this parameter is a counter that will be referenced by the
86 'count' attribute in another parameter.
87 count_scale - literal value scale factor for the 'count' attribute.
88 See ProgramParameters4dvNV for an example.
89 output - this parameter is used to store the output of the function.
90 variable_param - name of parameter used to determine the number of
91 elements referenced by this parameter. This should be the name of a
92 single enum parameter. Most of the gl*Parameter[if]v functions use
93 this. Additionally, the enums that can be passed should be properly
94 annotated.
95 img_width / img_height / img_depth / img_extent - name of parameters
96 (or hardcoded integer) used for the dimensions of pixel data.
97 img_xoff / img_yoff / img_zoff / img_woff - name of parameters used
98 for x, y, z, and w offsets of pixel data.
99 img_format - name of parameter used as the pixel data format.
100 img_type - name of parameter used as the pixel data type.
101 img_target - name of parameter used as a texture target. Non-texture
102 pixel data should hardcode 0.
103 img_send_null - boolean flag to determine if blank pixel data should
104 be sent when a NULL pointer is passed. This is only used by
105 TexImage1D and TexImage2D.
106 img_null_flag - boolean flag to determine if an extra flag is used to
107 determine if a NULL pixel pointer was passed. This is used by
108 TexSubImage1D, TexSubImage2D, TexImage3D and others.
109 img_pad_dimensions - boolean flag to determine if dimension data and
110 offset data should be padded to the next even number of dimensions.
111 For example, this will insert an empty "height" field after the
112 "width" field in the protocol for TexImage1D.
113
114 glx:
115 rop - Opcode value for "render" commands
116 sop - Opcode value for "single" commands
117 vendorpriv - Opcode value for vendor private (or vendor private with
118 reply) commands
119 large - set to "true" of the render command can use RenderLarge protocol.
120 doubles_in_order - older commands always put GLdouble data at the
121 start of the render packet. Newer commands (e.g.,
122 ProgramEnvParameter4dvARB) put the in the order that they appear
123 in the parameter list.
124 always_array - some single commands take reply data as an array or as
125 return value data (e.g., glGetLightfv). Other single commands take
126 reply data only as an array (e.g., glGetClipPlane).
127 handcode - some functions are just too complicated to generate
128 (e.g., glSeperableFilter2D) or operate only on client-side data
129 (e.g., glVertexPointer) and must be handcoded.
130 ignore - some functions have an entry in the dispatch table, but aren't
131 suitable for protocol implementation (e.g., glLockArraysEXT). This
132 also applies to functions that don't have any GLX protocol specified
133 (e.g., glGetFogFuncSGIS).
