Function SDL_strndup

pub unsafe extern "C" fn SDL_strndup(
    str: *const i8,
    maxlen: usize,
) -> *mut i8
Available on crate feature dep_sdl3 only.
Expand description

Allocate a copy of a string, up to n characters.

This allocates enough space for a null-terminated copy of str, up to maxlen bytes, using SDL_malloc, and then makes a copy of the string into this space.

If the string is longer than maxlen bytes, the returned string will be maxlen bytes long, plus a null-terminator character that isn’t included in the count.

The returned string is owned by the caller, and should be passed to SDL_free when no longer needed.

§Parameters

  • str: the string to copy.
  • maxlen: the maximum length of the copied string, not counting the null-terminator character.

§Return value

Returns a pointer to the newly-allocated string.

§Thread safety

It is safe to call this function from any thread.

§Availability

This function is available since SDL 3.2.0.
