Try the following program:
#include <sys/types.h>
#include <sys/stat.h>
#include <errno.h>
main()
{
struct stat sb;
errno = 0;
printf( "lstat(fred) = %d\n", lstat( "fred", &sb));
perror( "lstat");
}
If "fred" exists in the current directory, you would expect that errno
would not have been modified, and the output will be:
lstat(fred) = 0
lstat: Undefined error: 0
However, what comes out instead is:
lstat(fred) = 0
lstat: No such file or directory
Indicating that lstat is diddling errno when it shouldn't be.
8-(.
