NAME

6       getdirentries  - get directory entries in a filesystem-independent for‐
7       mat
8

SYNOPSIS

10       #include <dirent.h>
11
12       ssize_t getdirentries(int fd, char *buf, size_t nbytes , off_t *basep);
13
14   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
15
16       getdirentries():
17           Since glibc 2.19:
18               _DEFAULT_SOURCE
19           Glibc 2.19 and earlier:
20               _BSD_SOURCE || _SVID_SOURCE
21

DESCRIPTION

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

RETURN VALUE

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.
31

ERRORS
