Expand description

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_INHERITED, 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_GetProcessInput(), standard output will be available as SDL_PROP_PROCESS_STDOUT_POINTER and allows SDL_ReadProcess() and SDL_GetProcessOutput(), 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.

§Availability
