getdirentries(3) Library Functions Manual getdirentries(3)
getdirentries - get directory entries in a filesystem-independent
format
Standard C library (libc, -lc)
#include <dirent.h>
ssize_t getdirentries(size_t nbytes;
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
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.
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.
See the Linux library source code for details.
For an explanation of the terms used in this section, see
attributes(7).
