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

Perfect,

 

               You eventually landed on using _mktemp_s which is what
described in the first link I provided you with and is what I was hoping for
Windows.

 

Thanks a lot,

Maurizio

mktemp() is useful, but is in in the unix world general strongly 
discouraged in favor of mkstemp(). The problem with mktemp()  + file-create 
is, that in the time between the pathname is constructed and the file is
created,
another process might have created a file with the same name. mkstemp() is 
actually guaranteed to create a unique file. 

For the time being, i've commited a small implementation of mkstemp() for
windows,
that opens files with O_EXCL, which should be a first approximation.
However,
it's not tested, please test it and don't be surprised, if it needs more
tweaks
(maybe my flag settings are too restrictive).

all the best

No, it is not.  mktemp and friends merely generate a file name, while
mkstemp also opens the file and returns a file handle.  So yes, you
could use mktemp as part of an implementation of mkstemp, but they do
are not replacements for each other.
