Function SDL_strlen

pub unsafe extern "C" fn SDL_strlen(str: *const i8) -> usize

Available on crate feature dep_sdl3 only.

This works exactly like strlen() but doesn’t require access to a C runtime.

Counts the bytes in str, excluding the null terminator.

If you need the length of a UTF-8 string, consider using SDL_utf8strlen().

Parameters

Return value

Returns the length (in bytes, excluding the null terminator) of src.

Thread safety

It is safe to call this function from any thread.

Availability
