| are declared in the header <code class="literal">gprintf.h</code> which is not included in <code class="literal">glib.h</code> |
| (otherwise using <code class="literal">glib.h</code> would drag in <code class="literal">stdio.h</code>), so you'll have to |
| explicitly include <code class="literal"><glib/gprintf.h></code> in order to use the GLib |
| <code class="function">printf()</code> functions.</p> |
| <div class="refsect3"> |
| <a name="string-precision"></a><h4>String precision pitfalls</h4> |
| <p>While you may use the <code class="function">printf()</code> functions to format UTF-8 strings, |
| notice that the precision of a %Ns parameter is interpreted |
| as the number of bytes, not characters to print. On top of that, |
| the GNU libc implementation of the <code class="function">printf()</code> functions has the |
| "feature" that it checks that the string given for the %Ns |
| parameter consists of a whole number of characters in the current |
| encoding. So, unless you are sure you are always going to be in an |
| UTF-8 locale or your know your text is restricted to ASCII, avoid |
| using %Ns. If your intention is to format strings for a |
| certain number of columns, then %Ns is not a correct solution |
| anyway, since it fails to take wide characters (see <a class="link" href="glib-Unicode-Manipulation.html#g-unichar-iswide" title="g_unichar_iswide ()"><code class="function">g_unichar_iswide()</code></a>) |
| into account.</p> |
| <p>Note also that there are various <code class="function">printf()</code> parameters which are platform |
| dependent. GLib provides platform independent macros for these parameters |
| which should be used instead. A common example is <a class="link" href="glib-Basic-Types.html#G-GUINT64-FORMAT:CAPS" title="G_GUINT64_FORMAT"><code class="literal">G_GUINT64_FORMAT</code></a>, which |
| should be used instead of <code class="literal">%llu</code> or similar parameters for formatting |
| 64-bit integers. These macros are all named <code class="literal">G_*_FORMAT</code>; see |
| <a class="link" href="glib-Basic-Types.html" title="Basic Types">Basic Types</a>.</p> |

| <em class="parameter"><code>search_term</code></em> |
| and <em class="parameter"><code>potential_hit</code></em> |
| . ASCII alternates are never taken |
| for <em class="parameter"><code>search_term</code></em> |
| but will be taken for <em class="parameter"><code>potential_hit</code></em> |
| according to |
| the value of <em class="parameter"><code>accept_alternates</code></em> |
| .</p> |
| <p>A hit occurs when each folded token in <em class="parameter"><code>search_term</code></em> |
| is a prefix of a |
| folded token from <em class="parameter"><code>potential_hit</code></em> |
| .</p> |
| <p>Depending on how you're performing the search, it will typically be |
| faster to call <a class="link" href="glib-String-Utility-Functions.html#g-str-tokenize-and-fold" title="g_str_tokenize_and_fold ()"><code class="function">g_str_tokenize_and_fold()</code></a> on each string in |

| perform lookups into that index.</p> |
| <p>As some examples, searching for "fred" would match the potential hit |
| "Smith, Fred" and also "Frédéric". Searching for "Fréd" would match |
| "Frédéric" but not "Frederic" (due to the one-directional nature of |
| accent matching). Searching "fo" would match "Foo" and "Bar Foo |
| Baz", but not "SFO" (because no word as "fo" as a prefix).</p> |

| <p>The problem with <a class="link" href="glib-String-Utility-Functions.html#g-strncasecmp" title="g_strncasecmp ()"><code class="function">g_strncasecmp()</code></a> is that it does |
| the comparison by calling <code class="function">toupper()</code>/<code class="function">tolower()</code>. These functions |
| are locale-specific and operate on single bytes. However, it is |
| impossible to handle things correctly from an internationalization |
| standpoint by operating on bytes, since characters may be multibyte. |
| Thus <a class="link" href="glib-String-Utility-Functions.html#g-strncasecmp" title="g_strncasecmp ()"><code class="function">g_strncasecmp()</code></a> is broken if your string is guaranteed to be |
| ASCII, since it is locale-sensitive, and it's broken if your string |
| is localized, since it doesn't work on many encodings at all, |
| including UTF-8, EUC-JP, etc.</p> |
| <p> There are therefore two replacement techniques: <a class="link" href="glib-String-Utility-Functions.html#g-ascii-strncasecmp" title="g_ascii_strncasecmp ()"><code class="function">g_ascii_strncasecmp()</code></a>, |
| which only works on ASCII and is not locale-sensitive, and |
| <a class="link" href="glib-Unicode-Manipulation.html#g-utf8-casefold" title="g_utf8_casefold ()"><code class="function">g_utf8_casefold()</code></a> followed by <code class="function">strcmp()</code> on the resulting strings, |
| which is good for case-insensitive sorting of UTF-8.</p> |
| </div> |
| <p>A case-insensitive string comparison, corresponding to the standard |
| <code class="function">strncasecmp()</code> function on platforms which support it. It is similar |
