[PATCH v3] getdents.2: Use appropriate types

[Alejandro Colomar]

getdents():
This function has no glibc wrapper.
As such, we should use the same types the Linux kernel uses:
Use 'long' as the return type.

getdents64():
The glibc wrapper uses:
ssize_t getdents64(int, void *, size_t);

Hi Michael,

Sorry, I'm being a bit distracted these days :)
It should be good enough now, I think.

Cheers,

Alex
