Read array from array of offsets

[muted solar]

I have an array of offsets, each element of which points to an element of the actual data I want to read.

Here's some pseudocode:

u32 count = read_u32()

u32 offsets[count]
for i in 0..count:
  offsets[i] = read_u32()

data_t data[count]
for i in 0..count:
  fseek(offsets[i])
  data[i] = read_data_t()

I've tried making an array of pointers, but either there's no syntax for that, or I'm doing it wrong.

struct data_t {
  ...
}

struct data_pointer {
  u32 offset
  data_t data @ offset;
}

struct file {
  u32 count;
  data_pointer pointers[count];
}

this is how i would do it

and then place the file at the desired location

Thanks for the quick reply, but that's not exactly what I want.
There is a contiguous array of offsets followed by a contiguous array of data.

it's offsets... data..., not {offset, data}...

this would work though, this does not place the data, it places the data pattern at the offset

not in the struct

ohh, true

I'm dumb

[austere magnet]

nah its fine

[muted solar]

alright, thank you very much!

[muted solar]

is there a way I can make offset relative to offsetof(file)?

[austere magnet]

they are

oh wait

no

just do

data_t data @ offset + addressof(parent);

i think this should work

[muted solar]

it does!
