# SDL_GetEnvironment

Get the process environment.

## Header File

Defined in [<SDL3/SDL_stdinc.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h)

## Syntax

```c
SDL_Environment * SDL_GetEnvironment(void);
```

## Return Value

([SDL_Environment](SDL_Environment) *) Returns a pointer to the environment
for the process or NULL on failure; call [SDL_GetError](SDL_GetError)() for
more information.

## Remarks

This is initialized at application start and is not affected by setenv()
and unsetenv() calls after that point. Use
[SDL_SetEnvironmentVariable](SDL_SetEnvironmentVariable)() and
[SDL_UnsetEnvironmentVariable](SDL_UnsetEnvironmentVariable)() if you want
to modify this environment, or [SDL_setenv_unsafe](SDL_setenv_unsafe)() or
[SDL_unsetenv_unsafe](SDL_unsetenv_unsafe)() if you want changes to persist
in the C runtime environment after [SDL_Quit](SDL_Quit)().

## Thread Safety

It is safe to call this function from any thread.

## Version

This function is available since SDL 3.1.3.
