[naviserver-devel] no mkstemp() on Windows, use TclpCreateTempFile()?

[Andrew P. <at...@pi...>]

mkstemp() does not exist on Windows, and Naviserver uses it in three
places:

  $ find . -name "*.[ch]" -print | xargs grep -in mkstemp 
  ./nsd/adpeval.c:1183:    fd = mkstemp(debugfile); 
  ./nsd/tclhttp.c:426:                fd = mkstemp(httpPtr->spoolFileName); 
  ./nsd/driver.c:2301:            sockPtr->tfd = mkstemp(sockPtr->tfile); 

We could stick in our own mkstemp() implementation.  Some starting
points for that may be:

  http://stackoverflow.com/questions/6036227/mkstemp-implementation-for-win32 
  http://sourceforge.net/p/mingw/bugs/2003/ 

But Tcl 8.4 and later already have TclpCreateTempFile() (two separate
implementations for Unix and Windows), which seems to solve the same
problem.  It returns a TclFile object, not a file descriptor.

Can/should Naviserver's existing users of mkstemp() be modified to
instead work with TclpCreateTempFile()?  Or will that not quite work,
and we should borrow some of the Windows version of TclpCreateTempFile()
for direct use in Naviserver?
