Functions

void scan_iff(const void *iff_binary, int file_size, unsigned long *offsets, unsigned long *sizes)

parse a BEAM/IFF file and build a sections offsets table

Read a buffer containing a BEAM module file and set all found IFF sections into offsets array.

Parameters:
  • iff_binary – is BEAM module data.

  • file_size – is the BEAM module size in bytes.

  • offsets – all the relative offsets, each entry will be set to the offset of a different IFF section.

  • sizes – the computed sections sizes.

int iff_is_valid_beam(const void *beam_data)

Returns 1 if pointed binary is valid BEAM IFF.

Checks if the pointed binary has a valid BEAM IFF header.

Parameters:
  • beam_data – a pointer to the beam_data binary

Returns:

1 if beam_data points to a valid binary, otherwise 0 is returned.
