| /* The terminfo database structure is private to us, | |||||
| * so it's documented here. | |||||
| * terminfo defines the largest number as 32767 and the largest | |||||
| * compiled entry as 4093 bytes long. | |||||
| * Thus, we store all numbers as uint16_t, including string length. | |||||
| * All strings are prefixed by length, including the null terminator. | |||||
| * The largest string length we can handle is 65535 bytes, | |||||
| * including the null terminator. | |||||
| * The largest capability block we can handle is 65535 bytes. | |||||
| * This means that we exceed the current terminfo defined limits. | |||||
| * | |||||
| * Version 1 capabilities are defined as: | |||||
| * header byte (always 1) | |||||
| * name | |||||
| * description, | |||||
| * cap length, num flags, index, char, | |||||
| * cap length, num numbers, index, number, | |||||
| * cap length, num strings, index, string, | |||||
| * cap length, num undefined caps, name, type (char), flag, number, string | |||||
| * | |||||
| * Version 2 entries are aliases and defined as: | |||||
| * header byte (always 2) | |||||
| * 32bit id of the corresponding terminal in the file | |||||
| * name | |||||
| * | |||||
| * The database itself is created using cdbw(3) and the numbers are | |||||
| * always stored as little endian. | |||||
