Synopsis

int readdir(unsigned int fd, struct old_linux_dirent *dirp,           
unsigned int count);

Note: There is no glibc wrapper for this system call; see NOTES.

Description

readdir() reads one old_linux_dirent structure from the directory referred to by the file descriptor fd into the buffer pointed to by dirp. The argument count is ignored; at most one old_linux_dirent structure is read.

The old_linux_dirent structure is declared as follows:

struct old_linux_dirent {
    long  d_ino;              /* inode number */
    off_t d_off;              /* offset to this old_linux_dirent */
    unsigned short d_reclen;  /* length of this d_name */
    char  d_name[NAME_MAX+1]; /* filename (null-terminated) */
}

d_ino is an inode number. d_off is the distance from the start of the directory to this old_linux_dirent. d_reclen is the size of d_name, not counting the terminating null byte (aq\0aq). d_name is a null-terminated filename.

Return Value

EFAULT
