The Process Properties pane shows the process's startup arguments, and the values of the process's IDs: real user, effective user, real group, and effective group.
The process arguments are the arguments that were used to start your selected process as they were passed to your process, but not necessarily as you typed them. For example, if you type ws *.c, the pane might show ws cursor.c io.c my.c phditto.c swaprelay.c, since the shell expands the *.c before launching the program.
The process ID values determine which permissions are used for your program. For example, if you start a process as root, but use the seteuid and setegid functions to run the program as the user jsmith, the program runs with jsmith's permissions. By default, all programs launched from the IDE run as root.
