SDL_isprint - Man Page

#include <SDL3/SDL_stdinc.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 ' ' (0x20) through '~' (0x7E) as true.

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.

SDL_isgraph(3).
