/**
* \file struct.h
* Add functionality similar to the python "struct" module to make it easier
* to read and write .iso structures.
*
* The following conversions are supported:
* B uint8_t, the arg should be (uint8_t*)
* H uint16_t, the arg should be (uint16_t*)
* L uint32_t, the arg should be (uint32_t*)
* S a 7-byte timestamp, the arg should be (time_t*)
* T a 17-byte timestamp, the arg should be (time_t*)
* x ignored field, no arg should be specified
*
* Any of the first 3 conversions may be preceded by a endian specifier:
* < little-endian
* > big-endian
* = both-endian (ie. according to ecma119 7.2.3 or 7.3.3)
*
* Each conversion specifier may also be preceded by a length specifier. For
* example, "<5L" specifies an array of 5 little-endian 32-bit integers. Note
* that "=L" takes 8 bytes while "<L" and ">L" each take 4.
*
* You can use a lower-case conversion specifier instead of an upper-case one
* to signify that the (multi-element) conversion should stop when a zero is
* reached. This is useful for writing out NULL-terminated strings. Note that
* this has no effect when unpacking data from a struct.
