2807 | archive header (armap). The byte ordering of the armap and the | |
2808 | contents are encoded in the name of the armap itself. At least for | |
2809 | now, we only support archives with the same byte ordering in the | |
2810 | armap and the contents. | |
2811 | ||
2812 | The first four bytes in the armap are the number of symbol | |
2813 | definitions. This is always a power of two. | |
2814 | ||
2815 | This is followed by the symbol definitions. Each symbol definition | |
2816 | occupies 8 bytes. The first four bytes are the offset from the | |
2817 | start of the armap strings to the null-terminated string naming | |
2818 | this symbol. The second four bytes are the file offset to the | |
2819 | archive member which defines this symbol. If the second four bytes | |
2820 | are 0, then this is not actually a symbol definition, and it should | |
2821 | be ignored. | |
2822 | ||
2823 | The symbols are hashed into the armap with a closed hashing scheme. | |
2824 | See the functions below for the details of the algorithm. | |
