17 Since glibc 2.19:
18 _DEFAULT_SOURCE
19 Glibc 2.19 and earlier:
20 _BSD_SOURCE || _SVID_SOURCE
21
23 Read directory entries from the directory specified by fd into buf. At
24 most nbytes are read. Reading starts at offset *basep, and *basep is
25 updated with the new position after reading.
26
28 getdirentries() returns the number of bytes read or zero when at the
29 end of the directory. If an error occurs, -1 is returned, and errno is
30 set appropriately.
