Function SDL_wcslen
pub unsafe extern "C" fn SDL_wcslen(wstr: *const u32) -> usize
Available on crate feature
dep_sdl3
only.Expand description
This works exactly like wcslen() but doesn’t require access to a C runtime.
Counts the number of wchar_t values in wstr
, excluding the null
terminator.
Like SDL_strlen
only counts bytes and not codepoints in a UTF-8 string,
this counts wchar_t values in a string, even if the string’s encoding is of
variable width, like UTF-16.
Also be aware that wchar_t is different sizes on different platforms (4 bytes on Linux, 2 on Windows, etc).
§Parameters
wstr
: The null-terminated wide string to read. Must not be NULL.
§Return value
Returns the length (in wchar_t values, excluding the null terminator) of
wstr
.
§Thread safety
It is safe to call this function from any thread.
§Availability
This function is available since SDL 3.2.0.
