<p>Build a unirpc packet. There are lots of arguments defined, pretty much all of them optional.</p>
|
|||
|
|
|
|||
|
|
<p>Header fields:.</p>
|
|||
|
|
<ul><li>
|
|||
|
|
<p>version_byte: The protocol version (this is always 0x6c in the protocol)</p>
|
|||
|
|
</li><li>
|
|||
|
|
<p>other_version_byte: Another version byte (always 0x01 in the protocol)</p>
|
|||
|
|
</li><li>
|
|||
|
|
<p>body_length_override: The length of the body (automatically calculated, normally)</p>
|
|||
|
|
</li><li>
|
|||
|
|
<p>argcount_override: If set, specifies a custom number of “args” (automatically calculated, normally)</p>
|
|||
|
|
</li></ul>
|
|||
|
|
|
|||
|
|
<p>Body fields:</p>
|
|||
|
|
<ul><li>
|
|||
|
|
<p>body_override: If set, use it as the literal body and ignore the rest of these</p>
|
|||
|
|
</li><li>
|
|||
|
|
<p>oldschool_data: The service supports two different types of serialized data; AFAICT, this field is just free-form string data that nothing really seems to support</p>
|
|||
|
|
</li><li>
|
|||
|
|
<p>args: An array of arguments (the most common way to pass arguments to an rpc call).</p>
|
|||
|
|
</li></ul>
|
|||
|
|
|
|||
|
|
<p>Args are an array of hashes with :type / :value Valid types: :integer - :value is the integer (32-bits) :string / :bytes - value is the string or nil :float - :value is just a 64-bit value</p>
|
|||
|
|
|
|||
|
|
<p>Integer and Float values also have an :extra field, which is sent where the string’s length would go - I think it’s normally set to uninitialized memory, so probably you never need it.</p>
|
|||
|
|
|
|||
|
|
<p>String values have a boolean :null_terminate field as well, in case you want to disable null-termination (the service uses the length field in some cases, and null termination in others, so it could be interesting)</p>
|
|||
|
|
|
|||
|
|
<p>Set :skip_header to not attach a header (some services require only a body)</p>
