[En-Nut-Discussion] %P in putf.c

[Dusan Ferbas]

Hi Ralph,

I tried to use your %P enhancement. When used with sprintf it works. When 
used with stream fprintf it sometimes does not work ? Because whole or part 
of some fprintf is lost (packet sniffer used just to be sure). Did somebody 
encounter something similar ?

When no %P is used then output stream is perfect ('#if 1' case - see below).

Thread has 1536 bytes stack size. Its usage can be monitored with html page 
similar to basemon's 'Nut/OS Threads'.

Example of call:
       PrintXmlLine(stream,SysContact_P,     gBoardDatap->sysContact);

---------
static void PrintXmlLine(FILE *stream, const prog_char * tag_Pp, u_char *argp)
{
#if 1
   u_char tag_buf[100];

   strncpy_P(tag_buf, tag_Pp, 100);
   fprintf_P(stream, PSTR("<%s>%s</%s>\n"), tag_buf, argp, tag_buf);
#else
   fprintf_P(stream, PSTR("<%P>%s</%P>\n"), tag_Pp, argp, tag_Pp);
#endif
}

   PrintXmlLine(stream, tag_Pp, arg_buf);
#else
   fprintf_P(stream, PSTR("<%P>%P</%P>\n"), tag_Pp, arg_Pp, tag_Pp);
#endif
}
