The operators return an int, either 0 or 1. ----------------- 6.5.8 Relational operators 6 Each of the operators < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to) shall yield 1 if the specified relation is true and 0 if it is false. 90) The result has type int 6.5.9 Equality operators 3 The == (equal to) and != (not equal to) operators are analogous to the relational operators except for their lower precedence. 91) Each of the operators yields 1 if the specified relation is true and 0 if it is false. The result has type int. For any pair of operands, exactly one of the relations is true. ----------------- _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
