getdirentries — get directory entries in a filesystem-independent format
ssize_t getdirentries(int fd, char *buf, size_t nbytes , off_t *basep);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
Since glibc 2.19:
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 appropriately.
See the Linux library source code for details.

Not in POSIX.1. Present on the BSDs, and a few other systems. Use opendir(3) and readdir(3) instead.
