The macro + * \c glxproto_3s generates a function that takes 3 scalars, such as + * \c glVertex3f. + * - A capital C follwed by a lower-case v means that a constant + * sized vector is passed. Macros of this type take an extra parameter, + * which is the size of the vector. The invocation + * 'glxproto_Cv(Vertex3fv, X_GLrop_Vertexfv, GLfloat, 3)' would generate the + * correct protocol for the \c glVertex3fv function. + * - A capital V followed by a lower-case v means that a variable sized + * vector is passed. The function generated by these macros will call + * a co-function to determine the size of the vector. The name of the + * co-function is generated by prepending \c __gl and appending \c _size + * to the base name of the function. The invocation + * 'glxproto_enum1_Vv(Fogiv, X_GLrop_Fogiv, GLint)' would generate the + * correct protocol for the \c glFogiv function. + * - One or more digits without a following letter means that a function + * taking the specified number of scalar parameters and a function with a + * vector parameter of the specified size should be generated. The letter + * v is automatically appended to the name of the vector-based function in + * this case. The invocation + * 'glxproto_3(Vertex3f, X_GLrop_Vertex3fv, GLfloat)' would generate the + * correct protocol for both \c glVertex3f and \c glVertex3fv. + * + * glxproto_void is a special case for functions that take no parameters + * (i.e., glEnd). + * + * An addition form is 'glxvendr_'. This is identical to the other forms + * with the exception of taking an additional parameter (to the macro) which + * is a vendor string to append to the function name. The invocation + * 'glxproto_3(Foo3f, X_GLrop_Foo3fv, GLfloat)' would generate the functions + * 'glFoo3fv' and 'glFoo3f', and the invocation + * 'glxvendr_3(Foo3f, X_GLrop_Foo3fv, GLfloat, EXT)' would generate the + * functions 'glFoo3fvEXT' and 'glFoo3fEXT'. + */ + +#define glxproto_void(name, rop) \ + void __indirect_gl ## name (void) \ + { \ + __GLX_DECLARE_VARIABLES();
