+<h4>Temporary Files on Windows</h4>
+
+<p>The tmpfile() function on windows requires that all temporary files be
+stored in the root folder. The antelope (yacc) tool in base was calling
+tmpfile() and this was causing problems at sites where win32 systems have
+remmotely mounted secure file systems. A wrapper function called "FILE *
+epicsTempFile()" that creates a temporary file on WIN32 with a name epicsNNN
+using one of the following paths was installed into libCom. It searches
+starting with (1) below and stops when it finds a specified path that exists.
+On POSIX systems, and systems that default to POSIX behavior, epicsTempFile()
+simply calls tmpfile(). </p>
