Function SDL_iconv_wchar_utf8

pub unsafe fn SDL_iconv_wchar_utf8(S: *const u32) -> *mut i8
Available on crate feature dep_sdl3 only.
Expand description

Convert a wchar_t string to UTF-8.

This is a helper macro that might be more clear than calling SDL_iconv_string directly. However, it double-evaluates its parameter, so do not use an expression with side-effects here.

§Parameters

  • S: the string to convert.

§Return value

Returns a new string, converted to the new encoding, or NULL on error.

§Availability

This macro is available since SDL 3.2.0.
