Then 44 * in glGet*(), we lookup the struct for the enum in question, and use 45 * the offset to get the int we need. 46 * 47 * Sometimes we need to look up a float, a boolean, a bit in a 48 * bitfield, a matrix or other types instead, so we need to track the 49 * type of the value in struct gl_context. And sometimes the value isn't in 50 * struct gl_context but in the drawbuffer, the array object, current texture 51 * unit, or maybe it's a computed value. So we need to also track 52 * where or how to find the value. Finally, we sometimes need to 53 * check that one of a number of extensions are enabled, the GL 54 * version or flush or call _mesa_update_state(). This is done by 55 * attaching optional extra information to the value description 56 * struct, it's sort of like an array of opcodes that describe extra 57 * checks or actions. 58 * 59 * Putting all this together we end up with struct value_desc below, 60 * and with a couple of macros to help, the table of struct value_desc 61 * is about as concise as the specification in the old python script. 62 */ 63 64#undef CONST 65 66#define FLOAT_TO_BOOLEAN(X) ( (X) ?
