It's a single equals sign and I believe you're testing a condition?
What's being tested is the value assigned to 'entry', which is, in
turn, the return value of readdir(). readdir() returns the next directory
entry in a stream, or NULL if it's run out of entries. Putting the
assignment inside the test for the while loop means that it will continue to
loop until readdir() runs out of directory entries, and then readdir() will
return NULL, which will be assigned to 'entry', and the loop, testing that
assigned value, will find it false and terminate. This is likely the desired
behavior.
