!!NAME getdents - get directory entries !!SYNOPSIS __#include <unistd.h>__ __#include <linux/types.h>__ __#include <linux/dirent.h>__ __#include <linux/unistd.h>__ __int getdents(unsigned int__ fd, __struct dirent *__ dirp, __unsigned int__ count __);__ !!DESCRIPTION getdents(2) reads several ''dirent'' structures from the directory pointed at by ''fd'' into the memory area pointed to by ''dirp''. The parameter ''count'' is the size of the memory area. The ''dirent'' structure is declared as follows: struct dirent { long d_ino; /* inode number */ off_t d_off; /* offset to next ''dirent'' */ unsigned short d_reclen; /* length of this ''dirent'' */ char d_name [[NAME_MAX+1]; /* file name (null-terminated) */ } ''d_ino'' is an inode number. ''d_off'' is the distance from the start of the directory to the start of the next ''dirent''. ''d_reclen'' is the size of this entire ''dirent. d_name'' is a null-terminated file name. This call supersedes readdir(2). !!RETURN VALUE On success, the number of bytes read is returned. On end of directory, 0 is returned. On error, -1 is returned, and ''errno'' is set appropriately. !!ERRORS ;[EBADF]: Invalid file descriptor ''fd''. ;[EFAULT]: Argument points outside the calling process's address space. ;[EINVAL]: Result buffer is too small. ;[ENOENT]: No such directory. ;[ENOTDIR]: File descriptor does not refer to a directory. !!CONFORMING TO SVr4, SVID. SVr4 documents additional [ENOLINK], [EIO] error conditions. !!SEE ALSO readdir(2), readdir(3)
