# SDL_isgraph

Report if a character is any "printable" except space.

## Header File

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

## Syntax

```c
int SDL_isgraph(int x);
```

## Function Parameters

|     |       |                           |
| --- | ----- | ------------------------- |
| int | **x** | character value to check. |

## Return Value

(int) Returns non-zero if x falls within the character class, zero
otherwise.

## Remarks

Be advised that "printable" has a definition that goes back to text
terminals from the dawn of computing, making this a sort of special case
function that is not suitable for Unicode (or most any) text management.

**WARNING**: Regardless of system locale, this is equivalent to
`(SDL_isprint(x)) && ((x) != ' ')`.

## Thread Safety

It is safe to call this function from any thread.

## Version

This function is available since SDL 3.1.3.
