Subject: a (documented) way to get the Ext2+ filesystem size?
How do I get the Ext2+ filesystem size (in blocks)?
Currently, I do it like:
static uint_fast64_t
e2fs_size (ext2_filsys e2)
{
uint_fast32_t hi
= (uint_fast32_t)e2->super->s_blocks_count_hi;
uint_fast32_t lo
= (uint_fast32_t)e2->super->s_blocks_count;
/* . */
return (((uint64_t)hi << 32) | lo);
}
However, it seems that there's no documentation for both the
ext2_filsys and struct ext2_super_block structure types, and
their respective member fields.
Am I safe with the code above?
