<h1> The <tt>skalibs/envalloc.h</tt> header </h1>
<p>
The following functions are declared in the <tt>skalibs/env.h</tt> header,
and implemented in the <tt>libskarnet.a</tt> or <tt>libskarnet.so</tt> library.
</p>
<h2> General information </h2>
<p>
<tt>envalloc.h</tt> is a supplement of <a href="env.html"><tt>env.h</tt></a>
header that lets one use <a href="stralloc.html">genallocs</a> of
<tt>char const *</tt> instead of fixed-size <tt>char const *[]</tt>.
</p>
<h2> Functions </h2>
<p>
<code>int envalloc_uniq (genalloc *v, char delim)</code><br>
Removes strings in the <em>v</em> that share the same prefix up to the first
<em>delim</em> character. For instance, if delim is <tt>=</tt>, duplicate
environment variables are removed. Returns the number of removed entries on
success, -1 (and sets errno) on failure.
</p>
<p>
<code>int envalloc_0 (genalloc *v)</code><br>
Appends a null pointer to <em>v</em>. Returns 1 on sucess, 0 (and sets errno)
on failure.
</p>
<p>
<tt>envalloc_make</tt> and <tt>envalloc_merge</tt> work exactly like their
<tt>env.h</tt> counterparts.
