Function SDL_strlcat

pub unsafe extern "C" fn SDL_strlcat(
    dst: *mut i8,
    src: *const i8,
    maxlen: usize,
) -> usize

Available on crate feature dep_sdl3 only.

Concatenate strings.

This function appends up to maxlen - SDL_strlen(dst) - 1 characters from src to the end of the string in dst, then appends a null terminator.

src and dst must not overlap.

If maxlen - SDL_strlen(dst) - 1 is less than or equal to 0, then dst is unmodified.

Parameters

• dst: The destination buffer already containing the first null-terminated string. Must not be NULL and must not overlap with src.
• src: The second null-terminated string. Must not be NULL, and must not overlap with dst.
• maxlen: The length (in characters) of the destination buffer.

Return value

Returns the length (in characters, excluding the null terminator) of the string in dst plus the length of src.

Thread safety

It is safe to call this function from any thread.

Availability

This function is available since SDL 3.2.0.
