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 go, 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 go, 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¶

RETURN VALUE¶

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