SDL_isgraph(3) SDL3 FUNCTIONS SDL_isgraph(3)

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

Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"
int SDL_isgraph(int x);

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)!='') .

character value to check.

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

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
