<h2>Synopsis</h2>

<h2>Prototype</h2>
<pre>
#include "ej.h"
int <b>ejOpen</b>(sym_fd_t variables, sym_fd_t functions);
</pre>
<h2>Parameters</h2>
<p><table width=90%>
<TR>
<TD width=40>variables
<TD> Symbol table for variables
<TR>
<TD width=40>functions

<h2>Description</h2>
<P>To use JavaScript, you must first open an interpreter session
with <i>ejOpen</i>. JavaScript interpreters usually have their own
variable and global function name space. To share variable or function
name space, pass a symbol table into <b>ejOpen</b> in the <i>variable</i>
or <i>function</i> parameters. If either of these parameters are set
to NULL, the symbol table will be created automatically.</P>
<p>Use <b>ejClose</b> to close the interpreter when finished.
<h2>Return Value</h2>
<p>Handle for the JavaScript interpreter.</p>
<h2>Example</h2>
<pre>
if (ejOpen(NULL, NULL)< 0) {
/* Cant open interpreter */
return -1;
}
</pre>
