The fchdir() function shall be equivalent to chdir() except that
sl@0
    31
the directory that is to be the new current working directory is
sl@0
    32
specified by the file descriptor fildes.A conforming application
sl@0
    33
can obtain a file descriptor for a file of type directory using 
sl@0
    34
open(), provided that the file status flags and access modes do 
sl@0
    35
not contain O_WRONLY or O_RDWR.
sl@0
    36
    
sl@0
    37
Upon successful completion, fchdir() shall return 0. Otherwise,
sl@0
    38
it shall return -1 and set errno to indicate the error. 
sl@0

Calls the reentrant version of the function.
