25 /* | |
26 * Interfaces available from the process control library, libproc. | |
27 * | |
28 * libproc provides process control functions for the /proc tools | |
29 * (commands in /usr/proc/bin), /usr/bin/truss, and /usr/bin/gcore. | |
30 * libproc is a private support library for these commands only. | |
31 * It is _not_ a public interface, although it might become one | |
32 * in the fullness of time, when the interfaces settle down. | |
33 * | |
34 * In the meantime, be aware that any program linked with libproc in this | |
35 * release of Solaris is almost guaranteed to break in the next release. | |
36 * | |
37 * In short, do not use this header file or libproc for any purpose. | |
