This section describes the base data types used in messages.
Intn(i)
An n bit integer in network byte order.
If i is specified it
is the literal value. Eg. Int16, Int32(42).
LimStringn(s)
A character array of exactly n bytes interpreted as a
null-terminated string. The zero-byte is omitted if there is
insufficient room. If s is specified it is the literal value.
Eg. LimString32, LimString64("user").
String(s)
A conventional C null-terminated string with no length
limitation.
If s is specified it is the literal value.
Eg. String, String("user").
Note: There is no predefined limit on the length of a string
that can be returned by the backend. Good coding strategy for a frontend
is to use an expandable buffer so that anything that fits in memory can be
accepted. If that's not feasible, read the full string and discard trailing
characters that don't fit into your fixed-size buffer.
Byten(c)
Exactly n bytes. If c is specified it is the literal
value. Eg. Byte, Byte1('\n').
