I had changed this from a for loop to a memset during an earlier
cleanup. This change was incorrect so revert it.
While here, clean up
Reported by: flo
- 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)
- Add const where helpful
- add missing 'static' for file-local functions
- use nitems where possible
- convert manual abort() to assert
- use strndup instead of homegrown version
Tested with clang, gcc7, and gcc9
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
- use bool instead of int [0]
- use calloc correctly [0]
(this also caught an incorrect sizeof argument) [1]
- use size_t over int [2]
- correct style
Reported by: pfg [0], scan-build [1], gcc [2]
- Prefer calloc over malloc. This is more predicable and we're not in a
performance sensitive context. [1]
- Remove bogus comment (obsolete from prior commit). [2]
- Remove void casts and type casts of NULL
- Remove redundant declaration of 'quit'
- Add additional const

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.

- Prefer using ansi prototypes rather than C prototypes
- Keep type on separate line from name of function
- Try to keep things const where possible. This will help get to WARNS=6
- switch to "bool" where it makes sense
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
We've been maintaining top(1) for a long time, and the upstream
hasn't existed/been used in similarly as long. Make it clear that we own
top(1)
Tested with 'make universe'. Everything passed except MIPS which failed
for unrelated reasons. Install also tested for amd64.
