NAME         top

       getdirentries - get directory entries in a filesystem-independent
       format

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #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         top

       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         top

       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         top

       See the Linux library source code for details.
