Use <dirent.h> instead of <sys/dir.h> Using <dirent.h> and struct dirent instead of <sys/dir.h> and struct direct is preferred and works on Android which lacks sys/dir.h. See: http://pubs.opengroup.org/onlinepubs/009695399/basedefs/dirent.h.html 2014-07-06 19:51:01 +05:30			`#include <dirent.h>`

library: cleanup of library includes The includes used to define a lot of things a library include should not. It was also a bit messy what was exposed in the library and what was not. get_pid_digits -> procps_pid_length and exported correctly MALLOC attribute move into relevant .c files NORETURN attribute moved to relevant .c, not used in library PURE attribute removed, it wasn't used KLONG/KLF/STRTOUKL were fixed for long, so now just use long HIDDEN attribute removed. It was for 3 functions. The PROCPS_EXPORT seems to do the same (opposite) thing. likely/unlikely removed from most places, its highly debateable this does anything useful as CPUs have gotten smarter about branches. Re-arranged the includes, ALL external programs should just #include <proc/procps.h> then proc/procps.h includes headers for files that have exported functions. procps.h and the headers it includes should not use items that are not exportable (e.g. hidden functions or macros) they go in procps-private.h 2016-04-16 12:33:57 +05:30			`#include <features.h>`
library: sysstat and vmstat api changes Use the standard libc declarations. For protecting the headers for C++ procps used to have its own defines, this change makes them use the standard libc ones. getstat() -> procps_stat_* vminfo() -> procps_vmstat_* These two components of the library now use the newer version of the API with less exposed global variables. The old methods are there for now. Signed-off-by: Craig Small <csmall@enc.com.au> 2015-06-20 03:13:02 +05:30			`__BEGIN_DECLS`

library: Replace smp_num_cpu with function Instead of exposing a variable smp_num_cpus that is updated with cpuinfo, use procps_cpu_count() which returns the same value. 2015-06-29 18:01:36 +05:30			`long procps_cpu_count(void);`
