Where is the U area.

[Amos Shapira]

Hello,
 I'm considering porting top(1) to Iris, and from looking at
 the work of a local guru who did a port for SunOS I saw that I'll have
 to find the U area of each process.

 Now, where is it? I think that knowing the virtual address will
 be a good start, but any further info (like how to read the U area
 through the proc structure) will be welcomed.

 Please e-mail responses.

Thanks,
Amos Shapira
