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: replace the troublesome '__BEGIN_DECLS' macro When 'newlib' was introduced, in the commit referenced below, the use of that glibc '__BEGIN_DECLS' macro was standardized. However, as issue #88 revealed, this may result in a fatal build error with other environments. So, this patch just trades that macro for the standard '#ifdef __cplusplus' conventions (thus avoiding use of all those '#include <features.h>' directives as well).

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);`
library: cleanup unused old functions The old getstat and meminfo functions and their globals are removed. Also page_size is now a function, procps_pagesize_get() 2015-07-01 17:38:02 +05:30			`long procps_hertz_get(void);`
			`int procps_loadavg(double av1, double av5, double *av15);`
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			`unsigned int procps_pid_length(void);`
