Code review: recursion in circular array, reduce two functions to one?
Hello,
I think there's an easier way to do this but can't seem to recall but given an array of animals[0...5] and an initial value is a random index in the array, here it's 3.
a quick brute force solution i came up with was two functions, i set a limit of 20 so it doesn't become a memory bomb. there would be some kind of other conditional break point.

Hello,
Please tell me if there is a better way to get the number of elements from an array that is passed to a function.
This is what works on Solaris 8 (ksh) but it looks odd:

b2='}'

Please excuse my ineptitude for a bit as I've been spoiled for the past few months with only writing perl code instead of C.
So ok, I've been thinking about some code to change the crc32 values that are held within central directory headers of zip files.
Because I'm lazy I decided to just... (3 Replies)
Hi All,
Could some one help me to reduce the code...

Let me know if there is a way to pass array to a funtion in ksh script.
function isPresent
{
typeset member
member=$1
dbList=$2
echo '$1:' $1
echo '$2' $dbList
The array will be at the second position....something like this
isPresent 12 <array>
if
then

I have a question on how can I assign a output of a function to a variable which is executed in background.
Here is my example
$ cat sample_program.sh
#!/bin/ksh
exec_func () {

v=`expr $1 + 100`
print $v
}
export OUT_ARR

for i in 1 2

OUT_ARR=`exec_func $i` &... (1 Reply)
I have the following code to count the number of how many times the name occurred in one file. The code is working fine and the output is exactly what I want. The problem is the real code has more than 50 names in function listname which cause function name to have more than 50 case ,and function... (14 Replies)

initstate
random(3M)random(3M)NAME
random(), srandom(), initstate(), setstate() - generate a pseudorandom number
SYNOPSIS DESCRIPTION
The and functions are random-number generators that have virtually the same calling sequence and initialization properties as the and func-
tions, but produce sequences that are more random. The low 12 bits generated by the function go through a cyclic pattern, while all the
bits generated by the function are usable. For example, produces a random binary value.
The function uses a nonlinear additive feedback random-number generator employing a default state array size of 31 long integers to return
successive pseudorandom numbers in the range from 0 to The period of this random-number generator is approximately 16 x The size of the
state array determines the period of the random-number generator. Increasing the state array size increases the period.
With 256 bytes of state information, the period of the random-number generator is greater than
Like the function, the function produces by default a sequence of numbers that can be duplicated by calling the function with a value of 1
as the seed.
The function initializes the current state array using the value of seed.
The and functions handle restarting and changing random-number generators. The function allows a state array, pointed to by the state
argument, to be initialized for future use. The size argument, which specifies the size in bytes of the state array, is used by the func-
tion to decide how sophisticated a random-number generator to use; the larger the state array, the more random the numbers. Values for the
amount of state information are 8, 32, 64, 128, and 256 bytes. Amounts less than 8 bytes return a NULL pointer, while other amounts are
rounded down to the nearest known value. The seed argument specifies a starting point for the random-number sequence and provides for
restarting at the same point. The function returns a pointer to the previous state information array.
Once a state has been initialized, the function allows switching between state arrays. The array defined by the state argument is used for
further random-number generation until the function is called or the function is called again. The function returns a pointer to the pre-
vious state array.
After initialization, a state array can be restarted at a different point in one of two ways:
The function can be used, with the desired seed, state array, and size of the array.
The function, with the desired state, can be used, followed by the function with the desired seed. The advantage of using both of
these functions is that the size of the state array does not have to be saved once it is initialized.
RETURN VALUE
The function returns the generated pseudorandom number.
The function returns no value.
Upon successful completion, the and functions return a pointer to the previous state array. Otherwise, a NULL pointer is returned.
ERRORS
If the function detects that the state information has been damaged, error messages are written to standard error.
