Get rid of “null argument where non-null required” gcc C.
I tried to upgrade to the latest single-header release of Catch as currently downloadable from the wiki, but got several compile errors. The first one was simple: you now need a semicolon after a CHECK statement which wasn't needed befor.
In GCC 7,-Wnonnull has been enhanced to detect a much broader set of cases of passing null pointers to functions that expect a non-null argument (those decorated with attribute nonnull). By taking.
Like every new GCC release, GCC6 introduces a lot of new useful warnings. My favorite is still -Wmisleading-indentation.But there are many more that have found various bugs. Not all of them are enabled by default, but it makes sense to enable as many as possible when writing new code.
Finding Tokens in a String (The GNU C Library) Next: Erasing Sensitive Data,. Subsequent calls to get additional tokens from the same string are indicated by passing a null pointer as the newstring argument. Calling strtok with another non-null newstring argument reinitializes the state information.
Conversions between NULL and non-pointer types now cause GCC to report a warning by default. Previously, these warnings were only displayed when explicitly using -Wconversion. To disable these warnings, use the new -Wno-conversion-null command line option.
