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(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.
