Function SDL_isgraph 

pub extern "C" fn SDL_isgraph(x: c_int) -> c_int

Report if a character is any “printable” except space.

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) != ' ').

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.
