If it is 1,a packet is received in the task level. Receiving packets in the interruptlevel requires about 10K bytes of memory, but minimize a risk of dropping packets. Receiving packets in the task level doesn't require extramemory, but might have a risk of dropping packets.<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./if_esmc.html#top">if_esmc</a></b><hr><a name="esmcattach"></a><p align=right><a href="rtnIndex.html"><i>Libraries : Routines</i></a></p></blockquote><h1><i>esmcattach</i>( )</h1> <blockquote></a></blockquote><h4>NAME</h4><blockquote> <p><strong><i>esmcattach</i>( )</strong> - publish the <b>esmc</b> network interface and initialize the driver.</p></blockquote><h4>SYNOPSIS</h4><blockquote><p><pre>STATUS esmcattach ( int unit, /* unit number */ int ioAddr, /* address of esmc's shared memory */ int intVec, /* interrupt vector to connect to */ int intLevel, /* interrupt level */ int config, /* 0: Autodetect 1: AUI 2: BNC 3: RJ45 */ int mode /* 0: rx in interrupt 1: rx in task(netTask) */ )</pre></blockquote><h4>DESCRIPTION</h4><blockquote><p>This routine attaches an <b>esmc</b> Ethernet interface to the network if thedevice exists.
