Hi,

I need some help please. I am trying to port some HP C++ code to Sun Solaris 8 with Forte Compiler 7.
I am trying to get the list of all processes running on my Sun server and all the process information.
I do this on HP using pstat_getproc function which stores all information in a structure pst_status.

On Sun Solaris I did managed to find a structure in pstatus, psinfo and lwpsinfo from procfs.h file. BUT I could not find any function which will return the all processes information in these structures at a given time.
My code which I use on HP is enclosed. I need to do simialr sort of thing so please help/sugget/guide me.
Thanks
Ravi
