[Lcd4linux-devel] small patch for plugin_mkfifo

[Claas H. <Cla...@li...>]

Hello,

here is a very small fix (against current svn) for the plugin_fifo. You 
need to clear errno after creating the FIFO. Without clearing the errno 
variable you will get an error in fiforead() like this:

[FIFO] Error 2: No such file or directory


babel@eisler:~/tmp/lcd4linux$ svn diff plugin_fifo.c
Index: plugin_fifo.c

     }
+    /* clear errno */
+    errno = 0;
     fd.created = 1;
     return 0;
 }
