I don't recall offhand, but IIRC there are C functions (and similar
functions for other languages) to return a _name_ that is good for a
tempfile. Instead of making a file from it, make a directory instead.
Hold on, I'll check my Linux Programming book to see if I find
mention of it.
Ok, here it is :
#include <stdio.h>
FILE* tmpfile( void ) ; /* here is what you are thinking of */
char* tmpnam( char* s ) ;
#include <unistd.h>
int mkstemp( char* template ) ;
char* mktemp( char* template ) ;
tmpfile() creates and returns a refernce to a file. You need a dir
instead. tmpnam() returns a string that is suitable for a temp file,
which could be used to create a dir instead.
The book then says that the functions probably give you a file in /tmp
or /var/tmp and shouldn't be used because those are public (vunerable)
directories.
There may already exist a "program" wrapper that is useable in a shell
script, or you could create one (unless you are already writing a C
app).
