i wrote the following function:
void test(void){ int myint; int64_t myintbig=412345678;
myint=myintbig; }
my question is: how (and where) do i tell xcode to generate an error on the above assignment?
-Wshorten-64-to-32This flag is like -Wconversion, but is specific to 64-bit data types. This flag causes GCC to issue a warning whenever a value is implicitly converted (truncated) from a 64-bit type to a 32-bit type. You should fix any warnings generated by this flag, as they are likely to be bugs.
