SDL_CreateProcessWithProperties(3)

NAME
SDL_CreateProcessWithProperties - Create a new process with the specified properties.

HEADER FILE
Defined in SDL3/SDL_process.h

SYNOPSIS
#include "SDL3/SDL.h"

SDL_Process * SDL_CreateProcessWithProperties(SDL_PropertiesID props);

DESCRIPTION
These are the supported properties:

• SDL_PROP_PROCESS_CREATE_ARGS_POINTER :
  an array of strings containing the program to run, any arguments, and a
  NULL pointer, e.g. const char *args[] = { "myprogram", "argument", NULL
  }. This is a required property.

• SDL_PROP_PROCESS_CREATE_ENVIRONMENT_POINTER :
  an SDL_Environment
 pointer. If this property is set,
  it will be the entire environment for the process, otherwise the current
  environment is used.

• SDL_PROP_PROCESS_CREATE_STDIN_NUMBER :
  an SDL_ProcessIO
 value describing where standard input
  for the process comes from, defaults to

SDL_PROCESS_STDIO_NULL .

• SDL_PROP_PROCESS_CREATE_STDIN_POINTER :
  an SDL_IOStream
 pointer used for standard input when

SDL_PROP_PROCESS_CREATE_STDIN_NUMBER is set to SDL_PROCESS_STDIO_REDIRECT .

• SDL_PROP_PROCESS_CREATE_STDOUT_NUMBER :
  an SDL_ProcessIO
 value describing where standard output
  for the process goes to, defaults to

SDL_PROCESS_STDIO_INHERITED .

• SDL_PROP_PROCESS_CREATE_STDOUT_POINTER :
  an SDL_IOStream
 pointer used for standard output when

SDL_PROP_PROCESS_CREATE_STDOUT_NUMBER is set to SDL_PROCESS_STDIO_REDIRECT .

• SDL_PROP_PROCESS_CREATE_STDERR_NUMBER :
  an SDL_ProcessIO
 value describing where standard error
  for the process goes to, defaults to

SDL_PROCESS_STDIO_INHERITED .

• SDL_PROP_PROCESS_CREATE_STDERR_POINTER :
  an SDL_IOStream
 pointer used for standard error when

SDL_PROP_PROCESS_CREATE_STDERR_NUMBER is set to SDL_PROCESS_STDIO_REDIRECT .

• SDL_PROP_PROCESS_CREATE_STDERR_TO_STDOUT_BOOLEAN :
  true if the error output of the process should be redirected into the
  standard output of the process. This property has no effect if

SDL_PROP_PROCESS_CREATE_STDERR_NUMBER is set.

• SDL_PROP_PROCESS_CREATE_BACKGROUND_BOOLEAN :
  true if the process should run in the background. In this case the
  default input and output is

SDL_PROCESS_STDIO_NULL and the exitcode of
  the process is not available, and will always be 0.

On POSIX platforms, wait() and waitpid(-1, ...) should not be called, and SIGCHLD should not be ignored or handled because those would prevent SDL from properly tracking the lifetime of the underlying process. You should use SDL_WaitProcess () instead.

FUNCTION PARAMETERS

props

( SDL_Process
 *) Returns the newly created and running process, or NULL if the process couldn't be created.
