annotate libinterp/octave-value/ov-fcn-handle.cc @ 19312:6ca096827123
Use tempname() rather than tmpnam() in core Octave.
* scripts/miscellaneous/tempname.m: Removed m-file as function is now C++.
* scripts/miscellaneous/tmpnam.m: New m-file is an alias that calls tempname.
* scripts/miscellaneous/module.mk: Add tmpnam.m to build system.
* io.txi: Place tempname, tempdir, P_tmpdir docstrings in section on temporary
files.
* system.txi: Remove tempname, tempdir, P_tmpdir docstrings from generic
system functions section of manual.
* dirfns.cc, dlmread.cc, md5sum.cc, ov-fcn-handle.cc: Replace instances
of tmpnam with tempname in BIST code.
* file-io.cc (Ftempname): Change DEFUNX for tmpnam to DEFUN for tempname.
Remove seealso links to tmpnam.
* ftp.m, playaudio.m, wavwrite.m, imformats.m, imread.m, imwrite.m, imageIO.m,
csvwrite.m, dlmwrite.m, fileread.m, importdata.m, textread.m, textscan.m,
genvarname.m, unpack.m, install.m, legend.m, __gnuplot_drawnow__.m,
copyobj.m, hgsave.m, print.m, __ghostscript__.m, __gnuplot_get_var__.m,
__gnuplot_ginput__.m, __gnuplot_print__.m: Replace tmpnam with tempname in
core code.
* build-sparse-tests.sh, io.tst, prefer.tst, system.tst: Replace tmpnam with
tempname in test code.
