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. + +SEE ALSO + true(1p), false(1p) |
