 * You can create a new subprocess with SDL_CreateProcess() and optionally read and write to it using SDL_ReadProcess() and SDL_WriteProcess(). If more advanced functionality like chaining input between processes is necessary, you can use SDL_CreateProcessWithProperties().
 *
 * You can get the status of a created process with SDL_WaitProcess(), or terminate the process with SDL_KillProcess().
 *

 * Description of where standard I/O should be directed when creating a process.
 *
 * If a standard I/O stream is set to SDL_PROCESS_STDIO_INHERIT, it will go to the same place as the application's I/O stream. This is the default for standard output and standard error.
 *
 * If a standard I/O stream is set to SDL_PROCESS_STDIO_NULL, it is connected to `NUL:` on Windows and `/dev/null` on POSIX systems. This is the default for standard input.
 *
 * If a standard I/O stream is set to SDL_PROCESS_STDIO_APP, it is connected to a new SDL_IOStream that is available to the application. Standard input will be available as `SDL_PROP_PROCESS_STDIN_POINTER` and allows SDL_WriteProcess(), standard output will be available as `SDL_PROP_PROCESS_STDOUT_POINTER` and allows SDL_ReadProcess(), and standard error will be available as `SDL_PROP_PROCESS_STDERR_POINTER` in the properties for the created process.
 *
 * If a standard I/O stream is set to SDL_PROCESS_STDIO_REDIRECT, it is connected to an existing SDL_IOStream provided by the application. Standard input is provided using `SDL_PROP_PROCESS_CREATE_STDIN_POINTER`, standard output is provided using `SDL_PROP_PROCESS_CREATE_STDOUT_POINTER`, and standard error is provided using `SDL_PROP_PROCESS_CREATE_STDERR_POINTER` in the creation properties. These existing streams should be closed by the application once the new process is created.
 *
 * In order to use an SDL_IOStream with SDL_PROCESS_STDIO_REDIRECT, it must have `SDL_PROP_IOSTREAM_WINDOWS_HANDLE_POINTER` or `SDL_PROP_IOSTREAM_FILE_DESCRIPTOR_NUMBER` set. This is true for streams representing files and process I/O.
