Hi,
I have implemented some changes in the linker code for some intermediate
processing.
For that I need to create a temporary directory, generate some
intermediate
files in it, process those files by calling a function. After processing
of the
intermediate files, I delete the intermediate files and the temporary
directory.
While this logic works fine in the linux, the temporary directory does
not get
deleted in cygwin.
/* ldmain.c */
main()
{
.
.
my_function();
.
.
delete tmp_directory;//I have to delete the tmp_directory only here
}
/* myfile.c */
my_function()
{
create tmp directory tmp_directory;
.
create intermediate files in the above directory; .
my_process_function(intermediate files);//processes the intermediate
files .
return;
}
my_process_function(files)
{
.
process the intermediate files;
.
delete the intermediate files;// I cannot delete the tmp_directory here
return;
}
After debugging using gdb, I found that in cygwin, the intermediate
files still
had some handlers open for it inspite of reaching till the end of the
main()
function in linker. Due to this, the temporary files get deleted only
after
exiting from the main. Hence as the temporary drectory is not empty till
then,
it cannot get deleted.
This behaviour is not seen in linux. Care has been taken in the code for
correct
opening and closing of the intermediate files.
Is this a known behavior in cygwin? Any inputs will be appreciated.
