This is 'effectively' converted into the following code in the wrapper file:
A file called example.sce will be created, which could be interpreted by the scilab. The code in the file is as following:
</p>
<div class="code"><pre>....
const int ICONST=42;
const char * SCONST="Hello World";
....
int ICONST_get (char *fname,unsigned long fname_len) {..}
int SCONST_get (char *fname,unsigned long fname_len) {..}
example.ICONST = 42
example.FCONST = 2.1828
example.CCONST = ascii(120)
example.CCONST2 = ascii(10)
example.SCONST = "Hello World"
example.SCONST2 = """Hello World"""
example.EXPR = 42+3*(2.1828)
example.iconst = 37
example.fconst = 3.14
.... </pre></div>
<p>It is easy to use the C constants as global variables:</p>
<p>It is easy to use the C constants after run the command "exec example.sce":</p>
<div class="targetlang"><pre>
scilab:1&gt; ICONST

scilab:1&gt; exec example.sce;
scilab:2&gt; example.ICONST

<H3><a name="Scilab_nn12"></a>27.3.5 Enums</H3>
<p> The way that deals with the enums is similar to the constants. For example:
</p>
<div class="code"><pre>%module example
typedef enum { RED, BLUE, GREEN } color;
</pre></div>
<p>
A file called example.sce will be created, which could be interpreted by the scilab. The code in the file is as following:
</p>
<div class="code"><pre>....
color.RED=0;
color.BLUE=color.RED + 1;
color.GREEN=color.BLUE + 1;
.... </pre></div>
<p>It is easy to use the enums after run the command "exec example.sce":</p>
<div class="targetlang"><pre>
scilab:1&gt; exec example.sce;
scilab:2&gt; printf(" RED = %i\n", color.RED);
RED = 0
scilab:3&gt; printf(" BLUE = %i\n", color.BLUE);
BLUE = 1
scilab:4&gt; printf(" GREEN = %i\n", color.GREEN);
GREEN = 2
</pre></div>
