Description of the C functions

Representation

The following conventions are used to represent the functions:

stenographic	For shell commands, function calls, programs and subprograms, as well as for constant values in plain text.
italics	For function names and parameters.

In the syntactic representation, the comment /* input */ stands for input parameter and the comment /* output */ for output parameter. These comments are no present at the structures, but on the lowest level at the parameters.
