Manpages - getdirentries.3

getdirentries - get directory entries in a filesystem-independent format

  #include <dirent.h>

  ssize_t getdirentries(int fd, char *restrict buf, 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).

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

*lseek*(2), *open*(2)
