C++ (Cpp) port_deny_multiple Examples

Example #1

File: serialVFD_io.c Project: mezcua/lcdproc

void
serialVFD_close_parallel (Driver *drvthis)
{
#ifdef HAVE_PCSTYLE_LPT_CONTROL
	PrivateData *p = drvthis->private_data;

	debug(RPT_DEBUG, "%s: Closing parallelport at: 0x%X", __FUNCTION__, p->port);
	if (port_deny_multiple(p->port,3)) {
		report(RPT_ERR, "%s: port_deny_multiple() of 0x%X failed (%s)\n", __FUNCTION__, p->port, strerror(errno));
	}
#endif
}

Example #2
