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 17:03:57 +10:00			`#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 07:43:02 +10:00			`__BEGIN_DECLS`

library: expanded/generalized memory allocation provisions A callback provision in the form of xalloc_err_handler (of type message_fn) was added to the alloc module. This change allowed a program like top, who alters the termios structure, to override the default fprint(stderr...) behavior in the event of an error. The new function xstrdup was also added for symmetry. 2011-11-16 10:49:02 -06:00

pmap: use correct types for memory allocation Fixes error which did not happen always. Changes of being affected by the bug where greater the more there where pids defined as pmap argument. The debian bug referral can almost certainly reproduce the problem, especially when tried multiple times in row. pmap: malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char ) &((av)->bins[((1) - 1) 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) \|\| ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.
