This section describes the base data types used in messages.
integer in network byte order (most significant byte
specified it is the exact value that will appear, otherwise
the value is variable. Eg. Int16, Int32(42).
An array of
each in network byte order. The array length
k is always determined by
an earlier field in the message. Eg. Int16[M].
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").
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.
bytes. If the field width
n is not a constant, it is
always determinable from an earlier field in the message.
c is specified
it is the exact value. Eg. Byte2, Byte1('\n').
