/proc File System and Watchpoints

The previous flat /proc file system has been restructured into a directory hierarchy that contains additional subdirectories for state information and control functions. It also provides a watchpoint facility to monitor access to, and modification of, data in the process address space. The new /proc file structure provides complete binary compatibility with the old /proc interface.

The adb(1) command has been modified to use the new /proc watchpoint facility. It now provides data breakpoints to cause the subject processes to stop on access to specified variables.

For more information, see the adb(1) man page.
