### Function

# GLib strndup

since: 2.0

#### Declaration

    gchar*
    g_strndup (
      const gchar* str,
      gsize n
    )

#### Description

Duplicates the first `n` bytes of a string, returning a newly-allocated buffer `n` + 1 bytes long which will always be nul-terminated. If `str` is less than `n` bytes long the buffer is padded with nuls. If `str` is `NULL` it returns `NULL`.

To copy a number of characters from a UTF-8 encoded string, use `g_utf8_strncpy()` instead.
