getdirentries(3)           Library Functions Manual           getdirentries(3)

NAME
       getdirentries - get directory entries in a filesystem-independent
       format

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       #include <dirent.h>

       ssize_t getdirentries(int fd, char buf[restrict .nbytes], size_t nbytes,
                             off_t *restrict basep);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       getdirentries():
           Since glibc 2.19:
               _DEFAULT_SOURCE
           glibc 2.19 and earlier:
               _BSD_SOURCE || _SVID_SOURCE

DESCRIPTION
       Read directory entries from the directory specified by fd into buf.  At
       most nbytes are read.  Reading starts at offset *basep, and *basep is
       updated with the new position after reading.

RETURN VALUE
       getdirentries() returns the number of bytes read or zero when at the
       end of the directory.  If an error occurs, -1 is returned, and errno is
       set to indicate the error.

ERRORS
       See the Linux library source code for details.
