fix warnings: expression result unused [-Wunused-value] In the assert()s take advantage of the fact that string constants ("string") are effectively of type 'const char []', which when used in an expression yield a non-NULL pointer. An assertion that should always fail can thus be formulated as: assert(!"fail); An assertion where a text message should be added to the expression can be written as such: assert("message" && expression); Signed-off-by: Giel van Schijndel <me@mortis.eu>
