NAME

       getdirentries - get directory entries in a filesystem-independent format

SYNOPSIS

       #include <dirent.h>

       ssize_t getdirentries(int fd, char *buf, size_t nbytes , off_t *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 appropriately.

ERRORS

       See the Linux library source code for details.
