<p>This section describes a number of utility functions for creating,
duplicating, and manipulating strings.</p>
<p>Note that the functions <a class="link" href="glib-String-Utility-Functions.html#g-printf" title="g_printf ()"><code class="function">g_printf()</code></a>, <a class="link" href="glib-String-Utility-Functions.html#g-fprintf" title="g_fprintf ()"><code class="function">g_fprintf()</code></a>, <a class="link" href="glib-String-Utility-Functions.html#g-sprintf" title="g_sprintf ()"><code class="function">g_sprintf()</code></a>,

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">&lt;glib/gprintf.h&gt;</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>

<p>Tokenises <em class="parameter"><code>string</code></em>

<p>A token is a non-empty sequence of alphanumeric characters in the

is non-<a class="link" href="glib-Standard-Macros.html#NULL:CAPS" title="NULL"><code class="literal">NULL</code></a> and some of the returned tokens

<p>The number of ASCII alternatives that are generated and the method
for doing so is unspecified, but <em class="parameter"><code>translit_locale</code></em>
(if specified) may
improve the transliteration if the language of the source string is

<p>Checks if a search conducted for <em class="parameter"><code>search_term</code></em>

<em class="parameter"><code>potential_hit</code></em>

<p>This function calls <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 both
<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

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 the search term and
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>At most <em class="parameter"><code>dest_size</code></em>
- 1 characters will be copied. Always nul-terminates
(unless <em class="parameter"><code>dest_size</code></em>

<code class="function">strncpy()</code>, this function doesn't pad <em class="parameter"><code>dest</code></em>

returns the size of the attempted result, strlen (src), so if
<em class="parameter"><code>retval</code></em>

<p>Caveat: <code class="function">strlcpy()</code> is supposedly more secure than <code class="function">strcpy()</code> or <code class="function">strncpy()</code>,

<p>Portability wrapper that calls <code class="function">strlcat()</code> on systems which have it,
and emulates it otherwise. Appends nul-terminated <em class="parameter"><code>src</code></em>
string to <em class="parameter"><code>dest</code></em>
,
guaranteeing nul-termination for <em class="parameter"><code>dest</code></em>
. The total size of <em class="parameter"><code>dest</code></em>
won't
exceed <em class="parameter"><code>dest_size</code></em>
.</p>
<p>At most <em class="parameter"><code>dest_size</code></em>
- 1 characters will be copied. Unlike <code class="function">strncat()</code>,
<em class="parameter"><code>dest_size</code></em>
is the full size of dest, not the space left over. This
function does not allocate memory. It always nul-terminates (unless
<em class="parameter"><code>dest_size</code></em>
== 0 or there were no nul characters in the <em class="parameter"><code>dest_size</code></em>
characters of dest to start with).</p>
<p>Caveat: this is supposedly a more secure alternative to <code class="function">strcat()</code> or
<code class="function">strncat()</code>, but for real security <a class="link" href="glib-String-Utility-Functions.html#g-strconcat" title="g_strconcat ()"><code class="function">g_strconcat()</code></a> is harder to mess up.</p>

<p>An implementation of the GNU <code class="function">vasprintf()</code> function which supports
positional parameters, as specified in the Single Unix Specification.
This function is similar to <a class="link" href="glib-String-Utility-Functions.html#g-vsprintf" title="g_vsprintf ()"><code class="function">g_vsprintf()</code></a>, except that it allocates a
string to hold the output, instead of putting the output in a buffer
you allocate in advance.</p>
