SDL_isprint(3) SDL3 FUNCTIONS SDL_isprint(3)

SDL_isprint - Report if a character is "printable".

Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"
int SDL_isprint(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 will only treat ASCII values

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.
