NAME
true - return true value
false - return false value
SYNOPSIS
true [ignored arguments]
false [ignored arguments]
DESCRIPTION
Optimised implementations of true(1p) and false(1p).
true and false shall do nothing, successfully and
unsuccessfully, respectively.
If your microarchitecture is especially supported,
true and false are implemented in assembler, without
a C runtime and only requires one page of memory.
If your microarchitecture is not especially supported,
true and false are implemented in C using only a
return statement in the main function. In this case,
a C runtime is used which slows down the program
significantly and it is usually required that somewhere
around 400 KB to 800 KB of memory is used (that is
about 150 pages.)
OPTIONS
None.
EXIT STATUS
true shall exit with the status 0.
false shall exit with any value other than 0.
In this implement false exits with the status 1.
RATIONALE
None.
NOTES
Your shell may have its own verions of true(1p)
and false(1p).
BUGS
None. These programs are about as simple as it gets.
