This is the long-awaited import of top into the base system (actually, the src/contrib/top part right now). This tools is simply too system- dependant to maintain it in the ports collection. 1997-03-23 18:51:21 +00:00			`/*`
top(1): Quiesce several warnings This is all warnings at level six (6) that are not char-subscripts, incompatible-pointer-types, sign-compare, switch, int-conversion, missing-variable-declarations, cast-qual, cast-align Some warnings that are fixed by this commit are: shadow, strict-prototypes, missing-prototypes, pointer-arith, unused-parameter, unused-const-variable, and several others 2018-05-20 02:14:27 +00:00			`* $FreeBSD$`

top: add -p option and p command to only show a single process Allow to show only a single process specified by PID. This could be done either by running top like 'top -p PID' or using the 'p' command inside top.

top(1): const poison top(1) has a number of issues with writing to const strings. Begin helping this along by marking easy cases as const. 2018-06-02 04:37:37 +00:00			`int atoiwi(const char *);`
top(1): Use uid_t for uid rather than 'int' Remove unneeded define while here. 2018-06-02 03:54:50 +00:00			`char *itoa(unsigned int);`
top(1): partial revert of r334517 In fixing issues with uid > INT_MAX, I broke the uid without username case. The latter is more important so return the old state. Discussed with: allanjude 2018-06-03 05:20:11 +00:00			`char *itoa7(int);`

top(1): Use strsep instead of homegrown alternative This replaces some complex, and not quite correct logic, with a more common strsep pattern. Reviewed by: mmacy (older version) 2018-06-04 03:16:24 +00:00			`const char * const argparse(char , int *);`

top(1): format_time, format_k, etc. - Use humanize_number for format_k and format_k2 - Fix some style nits in format_time 2018-06-13 08:52:09 +00:00			`const char *format_time(long);`
			`char *format_k(int64_t);`
top(1): another pass of cleanup - avoid the need to call a function to get size of known array. I'll likely re-arrange some of the indirect in a later to avoid the magic constants. - use correct type - add const - replace caddr_t with void*. This corrects an alignment warning. - remove duplicated include from immediately prior commit Under base clang we're now down to: - 3 warning in top.c, 1 warning in mahcine.c, 4 warning in display.c, - 1 warning in utils.c Tested with base clang, gcc7, gcc9, base gcc (mips) 2018-06-03 23:40:54 +00:00			`int string_index(const char string, const char const *array);`

Silence top(1) compiler warnings The contrib/top code is no longer maintained upstream (last pulled 16 years ago). The K&R-style followed by the code spews -Wimplicit-int and -Wreturn-type warnings, amongst others. This silences 131 warnings with as little modification as possible by adding necessary return types, definitions, headers, and header guards, and missing header includes. The 5 warnings that remain are due to undeclared ncurses references. I didn't include curses.h and term.h because there are several local functions and macros that conflict with those definitions.
