NAME

getdirentries - get directory entries in a filesystem-independent format

LIBRARY

Standard C library (libc, -lc)

SYNOPSIS

bash

#include <dirent.h>

bash

ssize_t getdirentries(int \nfd\n, char \nbuf\n[restrict .\nnbytes\n], size_t \nnbytes\n,\n
\n                      off_t *restrict \nbasep\n);

getdirentries():

    Since glibc 2.19:
\n
        _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.
