It can't handle paths containing "//":
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <sys/stat.h>
char buf[512];
void realpath_or_bust(const char* s)
{
const char* p = realpath(s, buf);
if (p)
puts(p);
else
perror(s);
}
int main()
{
rmdir("testdir/foo");
rmdir("testdir");
mkdir("testdir", S_IRWXU);
mkdir("testdir/foo", S_IRWXU);
realpath_or_bust("testdir/foo//..");
realpath_or_bust("testdir/foo//../foo");
}
This prints:
/home/jwakely/tmp/testdir/foo
testdir/foo//../foo: No such file or directory
