Field Detail

ident

public int ident

Bit31 is set if the state is coming, 0 if it is going.

dst

public int dst

The bits of destination dispatching are ascertained already before it is taken in the queue.

text

public java.lang.String text

The output and format controlling text. In C it should be a reference to a persistent, typical constant String. For a simple system the text can be left empty, using a null-reference.

timestamp

public final OS_TimeStamp timestamp

The time stamp of the message. It is detected before the message is queued.

values

public final VaArgBuffer values

Values from variable argument list. This is a special structure because the Implementation in C is much other than in Java. In Java it is simple: All arguments are of type Object, and the variable argument list is a Object[]. The memory of all arguments are handled in garbage collection. It is really simple. But in C there are some problems:

• Type of arguments
• Location of arguments: Simple numeric values are in stack (only call by value is possible) but strings (const char*) may be non persistent. No safety memory management is present.

Therefore in C language some things should be done additionally. See the special C implementation in VaArgList.c.
