[Plplot-devel] plbop() crash caused by moronic tmpfile() implementation in M$ W2000

[Joachim W. <wu...@cr...>]

Observation:
   Load file foo.dat from D:\path, plbop(), plot, everything works.
   Load same file from V:\path, plbop(), application crashes: "access =
violation".
   The only difference: drive V is read-only.
Explication:
   plbop() calls tmpfile(), which comes with libc. This is a posix =
routine that
   creates a temporary file. It looks as if the W2k implementation =
attempts to
   create the temporary file in just the last directory the application =
was in
   contact with.
Proposal:
   If I see correctly, in the whole of plplot there is only one call to =
tmpfile().
   Therefore we could easily either replace tmpfile() by an explicit =
fopen, or
   introduce a preprocessor switch and replaced tmpfile for Windows =
only.

Greetings, Joachim
