# 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 3.2.0. ## See Also - [SDL_isprint](SDL_isprint) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryStdinc](CategoryStdinc)
