In most cases this 83will just mean adding a '<glx ignore="true"/>' tag. 84 85param: 86 name - name of the parameter 87 type - fully qualified type (e.g., with "const", etc.) 88 client_only - boolean flag set on parameters which are interpreted only 89 by the client and are not present in the protocol encoding (e.g., 90 the stride parameters to Map1f, etc.) 91 count - for counted arrays (e.g., the 'lists' parameter to glCallLists), 92 the parameter or literal that represents the count. For functions 93 like glVertex3fv it will be a litteral, for others it will be one of 94 the parameters. 95 counter - this parameter is a counter that will be referenced by the 96 'count' attribute in another parameter. 97 count_scale - literal value scale factor for the 'count' attribute. 98 See ProgramParameters4dvNV for an example. 99 output - this parameter is used to store the output of the function. 100 variable_param - name of parameter used to determine the number of 101 elements referenced by this parameter. This should be the name of a 102 single enum parameter. Most of the gl*Parameter[if]v functions use 103 this. Additionally, the enums that can be passed should be properly 104 annotated. 105 img_width / img_height / img_depth / img_extent - name of parameters 106 (or hardcoded integer) used for the dimensions of pixel data. 107 img_xoff / img_yoff / img_zoff / img_woff - name of parameters used 108 for x, y, z, and w offsets of pixel data. 109 img_format - name of parameter used as the pixel data format. 110 img_type - name of parameter used as the pixel data type. 111 img_target - name of parameter used as a texture target. Non-texture 112 pixel data should hardcode 0. 113 img_send_null - boolean flag to determine if blank pixel data should 114 be sent when a NULL pointer is passed. This is only used by 115 TexImage1D and TexImage2D. 116 img_null_flag - boolean flag to determine if an extra flag is used to 117 determine if a NULL pixel pointer was passed. This is used by 118 TexSubImage1D, TexSubImage2D, TexImage3D and others. 119 img_pad_dimensions - boolean flag to determine if dimension data and 120 offset data should be padded to the next even number of dimensions. 121 For example, this will insert an empty "height" field after the 122 "width" field in the protocol for TexImage1D. 123 124glx: 125 rop - Opcode value for "render" commands 126 sop - Opcode value for "single" commands 127 vendorpriv - Opcode value for vendor private (or vendor private with 128 reply) commands 129 large - set to "true" of the render command can use RenderLarge protocol. 130 doubles_in_order - older commands always put GLdouble data at the 131 start of the render packet. Newer commands (e.g., 132 ProgramEnvParameter4dvARB) put the in the order that they appear 133 in the parameter list. 134 always_array - some single commands take reply data as an array or as 135 return value data (e.g., glGetLightfv). Other single commands take 136 reply data only as an array (e.g., glGetClipPlane). 137 handcode - some functions are just too complicated to generate 138 (e.g., glSeperableFilter2D) or operate only on client-side data 139 (e.g., glVertexPointer) and must be handcoded. 140 ignore - some functions have an entry in the dispatch table, but aren't 141 suitable for protocol implementation (e.g., glLockArraysEXT). This 142 also applies to functions that don't have any GLX protocol specified 143 (e.g., glGetFogFuncSGIS). 144--> 145
