How do I make this work:
void foo(uint8_t a[]) { ... }
foo({0x01, 0x02, 0x03});
It gives me an error:
error: cannot convert '<brace-enclosed initializer list>' to 'uint8_t* {aka unsigned char*}' for argument '1'
^
This worked for me, I had to change the function signature but it's actually better in my case as it statically checks the array length:
void foo(std::array<uint8_t, 3> a) { /* use a.data() instead of a */ }
foo({0x01, 0x02, 0x03}); // OK
foo({0x01, 0x02}); // Works, at least on GCC 4.9.1. The third value is set to zero.
foo({0x01, 0x02, 0x03, 0x04}); // Compilation error.
