duke@435 26 * Interfaces available from the process control library, libproc.
duke@435 27 *
duke@435 28 * libproc provides process control functions for the /proc tools
duke@435 29 * (commands in /usr/proc/bin), /usr/bin/truss, and /usr/bin/gcore.
duke@435 30 * libproc is a private support library for these commands only.
duke@435 31 * It is _not_ a public interface, although it might become one
duke@435 32 * in the fullness of time, when the interfaces settle down.
duke@435 33 *
duke@435 34 * In the meantime, be aware that any program linked with libproc in this
duke@435 35 * release of Solaris is almost guaranteed to break in the next release.
duke@435 36 *
duke@435 37 * In short, do not use this header file or libproc for any purpose.
