For a table - pointer, the low four bits of op is the number of index bits of - that table. For a length or distance, the low four bits of op - is the number of extra bits to get after the code. bits is - the number of bits in this code or part of the code to drop off - of the bit buffer. val is the actual byte to output in the case - of a literal, the base length or distance, or the offset from - the current table to the next table. Each entry is four bytes. */ -typedef struct { - unsigned char op; /* operation, extra bits, table bits */ - unsigned char bits; /* bits in this part of the code */ - unsigned short val; /* offset in table or code value */ -} code; - -/* op values as set by inflate_table(): - 00000000 - literal - 0000tttt - table link, tttt != 0 is the number of table index bits - 100eeeee - length or distance, eeee is the number of extra bits - 01100000 - end of block - 01000000 - invalid code - */ - -/* Maximum size of the dynamic table.
