<H3>MODULE SUMMARY</H3>
<DIV CLASS=REFBODY>
Interface module to the flex scanner linked in driver.
</DIV>
<H3>DESCRIPTION</H3>
<DIV CLASS=REFBODY>
<P> This module contains the public interface to the flex scanner
linked in driver. The flex scanner performs the scanning phase
of text message decoding.
<P> The flex scanner is written using a tool called <STRONG>flex</STRONG>.
In order to be able to compile the flex scanner driver, this
tool has to be available.
<P> By default the flex scanner reports line-number of an error.
But it can be built without line-number reporting. Instead
token number is used. This will speed up the scanning some
5-10%. Use <CODE>--disable-megaco-flex-scanner-lineno</CODE> when
configuring the application.
</DIV>
<H3>EXPORTS</H3>
<P><A NAME="start/0"><STRONG><CODE>start() -> {ok, Port} | {error, Reason}</CODE></STRONG></A><BR>
<DIV CLASS=REFBODY><P>Types:

</DIV>
</DIV>
<DIV CLASS=REFBODY>
<P> This function is used to start the flex scanner.
It locates the library and loads the linked in driver.
<P> Note that the process that calls this function <STRONG>must</STRONG>
be permament. If it dies, the port will exit and the driver unload.
