| | |
| (potentially) compressed arrays are endemic to most blocks contained in a p3d.
| |
| | |
| CompressedStruct
| |
| {
| |
| ulong Count;
| |
| <type> Array[Count];
| |
| };
| |
| | |
| | |
| if Count * sizeof(<type>) exceeds 1023 bytes the array is compressed. The '''resulting''' array will be expanded using lzh compression exactly as found in pbo's (for instance)
| |
| | |
| After de-compression, the Count remains the same because it is a count of the arraytype.
| |
| | |
| For uncompressed arrays (byte count < 1024) the Count and data are treated 'as is'.
| |
| | |
| | |
| Thus for various Array <types>
| |
| *ulong Array: > 255 // 1024 / sizeof(ulong)
| |
| *float thing[2]: > 127 // 1024 / 2*sizeof(float)
| |
| *SomeStructure: > // count * sizeof (SomeStructure) > 1023
| |
| | |
| | |
| Note that potentially compressed arrays in these structures only have an known output length. the decompressor therefore must work on infinite input length.

| Count corresponds to the number of concatenated strings. It is required, since, architecturally at least, one of more of the asciiz strings could be null.
