3.1.2 Argument Descriptions

Argument descriptions are given in the following format:

Object . Method (arg1, ..., argN) ! type1, ..., typeN => typeR

where

• 'Object' is the name of the sample instance defined in the first subsection of each class description
• 'Method' is the name of the method described
• 'arg1' through 'argN' are symbolic names for the arguments of the method
• 'type1' through 'typeN' are the types of 'arg1' through argN'
• 'typeR' is the type of value returned by the metod

In this context, 'type' is rather a weak attribute, since T3X is a typeless language. In many cases 'type' means a pointer to a structure having a specific layout.

The following types are used in this document:

Returned types may depend on the successful termination of a method. Such cases are listed, for example, as

Fdesc | -1

meaning 'either a file descriptor or minus 1'. Literal numbers in return types represent themselves.
