) -> PamojaStatus
Expand description

How many fragments a block of a given size takes, and how much padding the last one needs.

§Arguments

  • block_len - the block’s length in bytes.
  • frag_size - how many bytes each fragment carries.
  • out_nb_frag - receives the fragment count.
  • out_padding - receives the padding the last fragment carries.

§Returns

PamojaStatus::Ok on success.

§Errors

Returns PamojaStatus::InvalidArgument for a null pointer, a fragment size of zero, or a block needing more than PAMOJA_LORAWAN_MAX_FRAGMENTS fragments.

§Safety

Both out pointers must be writable.
