    <p>There are two strategies for safe string manipulation. The Linux / <a href="http://www.gnu.org/s/libc/">glibc</a> maintainers refuse to add safe functions, arguing that you should keep the length of your strings at hand and use <code>memcpy</code>. </p> <p>On the other hand, Mac OSX includes <code>strlcpy</code> and <code>strlcat</code> from BSD. <a href="http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man3/snprintf.3.html"><code>snprintf</code></a> and <a href="http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man3/asprintf.3.html"><code>asprintf</code></a> can be used on both platforms to much the same effect:</p> <pre><code>size_t strlcpy(char *d, char const *s, size_t n) { return snprintf(d, n, "%s", s); } size_t strlcat(char *d, char const *s, size_t n) { return snprintf(d, n, "%s%s", d, s); } </code></pre> <p>You could also consider using the BSD implementation <a href="http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/string/">found here</a>. If your code will be compiled on multiple platforms, you can test for the presence of glibc using <a href="http://predef.sourceforge.net/prelib.html">pre-defined library macros</a>:</p> <pre><code>#if defined __GNU_LIBRARY__ || defined __GLIBC__ size_t strlcpy(char *, char const *, size_t); size_t strlcat(char *, char const *, size_t); #endif </code></pre> <p>Conversion between character encodings is most easily handled using the <a href="http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man3/iconv.3.html"><code>iconv</code></a> interface.</p>

    1. COI needed a simple implementation of `strlcpy` and `strlcat` for a tool I'm porting to Linux, but **these do not work as expected**; when I swap to this implementation I'm getting large amounts of missing output. Replacing them with the BSD implementation (http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/string/) produces the expected results.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
