2 * Top - a top users display for Berkeley Unix
4 * Definitions for things that might vary between installations.
8 * The space command forces an immediate update. Sometimes, on loaded
9 * systems, this update will take a significant period of time (because all
10 * the output is buffered). So, if the short-term load average is above
11 * "LoadMax", then top will put the cursor home immediately after the space
12 * is pressed before the next update is attempted. This serves as a visual
13 * acknowledgement of the command. On Suns, "LoadMax" will get multiplied by
14 * "FSCALE" before being compared to avenrun[0]. Therefore, "LoadMax"
15 * should always be specified as a floating point number.
22 * "Table_size" defines the size of the hash tables used to map uid to
23 * username. The number of users in /etc/passwd CANNOT be greater than
24 * this number. If the error message "table overflow: too many users"
25 * is printed by top, then "Table_size" needs to be increased. Things will
26 * work best if the number is a prime number that is about twice the number
27 * of lines in /etc/passwd.
30 #define Table_size 20011
34 * "Nominal_TOPN" is used as the default TOPN when Default_TOPN is Infinity
35 * and the output is a dumb terminal. If we didn't do this, then
36 * installations who use a default TOPN of Infinity will get every
37 * process in the system when running top on a dumb terminal (or redirected
38 * to a file). Note that Nominal_TOPN is a default: it can still be
39 * overridden on the command line, even with the value "infinity".
42 #define Nominal_TOPN 18
46 #define Default_TOPN -1
50 #define Default_DELAY 2
54 * If the local system's getpwnam interface uses random access to retrieve
55 * a record (i.e.: 4.3 systems, Sun "yellow pages"), then defining
56 * RANDOM_PW will take advantage of that fact. If RANDOM_PW is defined,
57 * then getpwnam is used and the result is cached. If not, then getpwent
58 * is used to read and cache the password entries sequentially until the
59 * desired one is found.
61 * We initially set RANDOM_PW to something which is controllable by the
62 * Configure script. Then if its value is 0, we undef it.
