NAME¶
SDL_CreateThreadWithStackSize - Create a new thread with a specific stack size.
SYNOPSIS¶
#include "SDL3/SDL.h"
SDL_Thread * SDL_CreateThreadWithStackSize(SDL_ThreadFunction fn, const char *name, const size_t stacksize, void *data);
DESCRIPTION¶
SDL makes an attempt to report name to the system, so that debuggers can display it. Not all platforms support this.
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:

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).
FUNCTION PARAMETERS¶
RETURN VALUE¶
Returns an opaque pointer to the new thread object on success, NULL if the new thread could not be created; call SDL_GetError () for more information.
AVAILABILITY¶
This function is available since SDL 3.0.0.
