Something along the lines of the following, perhaps (assuming
ISO C99):
{
int only_with_blocks_p
= 0;
ext2_inode_scan scan;
{
errcode_t r
= ext2fs_open_inode_scan (e2, 0, &scan);
assert (r == 0);
}
FILE *out
= stdout;
errcode_t r;
ext2_ino_t ino;
struct ext2_inode inode;
int column;
/* FIXME: handle EXT2_ET_BAD_BLOCK_IN_INODE_TABLE, too */
while (((r = ext2fs_get_next_inode (scan, &ino, &inode)) == 0)
&& ino != 0) {
if (! only_with_blocks_p
|| ext2fs_inode_has_valid_blocks (inode)) {
/* skip over the inodes lacking valid blocks, if requested */
continue;
}
int n
= fprintf (out, " <%d>");
assert (n >= 0);
column += n;
/* NB: assuming that a typical inode number will be less than 9
decimal digits long, and that the terminal has 80 columns
*/
if (column >= 80 - 12) {
fputc ('\n', out);
}
}
/* FIXME: handle EXT2_ET_BAD_BLOCK_IN_INODE_TABLE, too */
assert (r == 0);
}
Or should I develop a proper patch?
