(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_isgraph

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

Header File

Syntax

int SDL_isgraph(int x);

Function Parameters

int

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.
