* MFC 283624,283630:jhb2015-10-011-0/+2
| | | | | | Export a list of VM objects in the system via a sysctl. The list can be examined via 'vmstat -o'. It can be used to determine which files are using physical pages of memory and how much each is using.

* Consensus between bde and pjd seemed to be that if the function namesghelmer2012-01-261-8/+8
| | | | | | are lined up, then any * after a long type should appear after the type instead of being in front of the function name on the following line.
* Make the comments consistent (capitalization, punctuation, andghelmer2012-01-261-6/+10

* Restore the parenthesis that are necessary around the constant values.ghelmer2012-01-261-7/+7
| | | | Requested by bde.
* Fix more disorder in prototypes and constants.ghelmer2012-01-161-46/+43
| | | | | | Fix header comments for each section of constants. Fix whitespace in #define lines. Fix unnecessary parenthesis in constants.
* Move struct pidfh definition into pidfile.c, and leave a forward declarationghelmer2012-01-121-12/+6
| | | | | | | | | for pidfh in libutil.h in its place. This allows us to hide the contents of the pidfh structure, and also allowed removal of the "#ifdef _SYS_PARAM_H" guard from around the pidfile_* function prototypes. Suggested by pjd.
* More prototype formatting fixes, struct member formatting fixes,ghelmer2012-01-121-10/+17

| | | | | | while here, fix missing parentheses of the return statement of pw_make. Approved by: des (mentor)
* Modify pw_copy:bapt2011-12-151-1/+7
| | | | | | | | | | | | | - if pw is NULL and oldpw is not NULL then the oldpw is deleted - if pw->pw_name != oldpw->pw_name but pw->pw_uid == oldpw->pw_uid then it renames the user add new gr_* functions so now gr_util API is similar to pw_util API, this allow to manipulate groups in a safe way.

* - Commit work from libprocstat project. These patches add support for runtimestas2011-05-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | file and processes information retrieval from the running kernel via sysctl in the form of new library, libprocstat. The library also supports KVM backend for analyzing memory crash dumps. Both procstat(1) and fstat(1) utilities have been modified to take advantage of the library (as the bonus point the fstat(1) utility no longer need superuser privileges to operate), and the procstat(1) utility is now able to display information from memory dumps as well. The newly introduced fuser(1) utility also uses this library and able to operate via sysctl and kvm backends. The library is by no means complete (e.g. KVM backend is missing vnode name resolution routines, and there're no manpages for the library itself) so I plan to improve it further. I'm commiting it so it will get wider exposure and review. We won't be able to MFC this work as it relies on changes in HEAD, which was introduced some time ago, that break kernel ABI. OTOH we may be able to merge the library with KVM backend if we really need it there. Discussed with: rwatson

| * Remove login(3), logout(3) and logwtmp(3) from libutil.ed2010-01-131-4/+0
| | | | | | | | | | | | | | | | | | | | These functions only apply to utmp(5). They cannot be kept intact when moving towards utmpx. The login(3) function would break, because its argument is an utmp structure. The logout(3) and logwtmp(3) functions cannot be used, since they provide a functionality which partially overlaps. Increment SHLIB_MAJOR to 9 to indicate the removal.
| * Make <libutil.h> work when included by itself.ed2009-12-021-0/+28
| | | | | | | | | | | | | | There are several reasons why it didn't work: - It was missing <sys/cdefs.h> for __BEGIN_DECLS. - It uses various primitive types that were not declared.
