This section describes the base data types used in messages.
Intn(i)
An n-bit integer in network byte
order (most significant byte first).
If i is specified it
is the exact value that will appear, otherwise the value
is variable. Eg. Int16, Int32(42).
Intn[k]
An array of kn-bit integers, each in network
byte order. The array length k
is always determined by an earlier field in the message.
Eg. Int16[M].
String(s)
A null-terminated string (C-style string). There is no
specific length limitation on strings.
If s is specified it is the exact
value that will appear, otherwise the value is variable.
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 the field
width n is not a constant, it is
always determinable from an earlier field in the message.
If c is specified it is the exact
value. Eg. Byte2, Byte1('\n').
