- *
- * Thread naming is a little complicated: Most systems have very small limits
- * for the string length (Haiku has 32 bytes, Linux currently has 16, Visual
- * C++ 6.0 has _nine_!), and possibly other arbitrary rules. You'll have to
- * see what happens with your system's debugger. The name should be UTF-8 (but
- * using the naming limits of C identifiers is a better bet). There are no
- * requirements for thread naming conventions, so long as the string is
- * null-terminated UTF-8, but these guidelines are helpful in choosing a name:
- *
- * https://stackoverflow.com/questions/149932/naming-conventions-for-threads
- *
- * If a system imposes requirements, SDL will try to munge the string for it
- * (truncate, etc), but the original string contents will be available from
- * SDL_GetThreadName().
- *
- * The size (in bytes) of the new stack can be specified. Zero means "use the
- * system default" which might be wildly different between platforms. x86
- * Linux generally defaults to eight megabytes, an embedded device might be a
- * few kilobytes instead. You generally need to specify a stack that is a
- * multiple of the system's page size (in many cases, this is 4 kilobytes, but
- * check your system documentation).
