Re: [LCP]directory test - resolved

Hi again,
I found it in the glibc manual.

int dirfd (DIR *dirstream)
.....          
The function dirfd returns the file descriptor associated with the 
directory stream dirstream. This descriptor can be used until the 
directory is closed with closedir. If the directory stream 
implementation is not using file descriptors the return value is -1.
...

Thanks,
Joachim Bauernberger
