Function SDL_isprint

pub unsafe extern "C" fn SDL_isprint(x: i32) -> i32
Available on crate feature dep_sdl3 only.
Expand description

Report if a character is “printable”.

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.

§Parameters

  • x: character value to check.

§Return value

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

§Thread safety

It is safe to call this function from any thread.

§Availability

This function is available since SDL 3.2.0.
