WebJun 11, 2014 · Assuming you know that on both machines the same byte order is used, but integers have a different default size, it might be more efficient to have a fixed width enum, as you can then communicate some bits, instead of a serialised message. The implementation may define typedef names intN_t, int_fastN_t, int_leastN_t, uintN_t, uint_fastN_t, and uint_leastN_t when N is not 8, 16, 32 or 64. Typedef names of the form intN_t may only be defined if the implementation supports an integer type of that width with no padding. Thus, … See more The following behavior-changing defect reports were applied retroactively to previously published C++ standards. See more Because C++ interprets a character immediately following a string literal as a user-defined string literal, C code such as printf("%"PRId64"\n",n); is invalid C++ and requires a space before PRId64. The C99 standard suggests … See more
