Hi,
I have a master BASH shell script where I define a bunch of variables:
$var1=why
$var2=is
$var3=(this so hard)
I would then like to call another shell script and pass these variables to it:
$script2 $var1 $var2 $var3
This works fine for var1 and var2. However, var3 is an array,... (9 Replies)
Hi experts,
I am here again with another Issue.
I need to pass the array as parameter / argument to another script.
I tried it as follows . ( I got this idea from the link )
$ cat test1.sh
#! /usr/bin/ksh
set -a arr1
echo "...In Test1...."
arr1="APPS_DEV"

Hi,
I have an output generated from a shell script like;
0x41,0xF2,0x59,0xDD,0x86,0xD3,0xEF,0x61,0xF2
How can I pass this value to the C function, as below;
int main(int argc, char *argv) {
unsigned char hellopdu={above value};
}

hi,
I have a array say
SAP_ARRAY="s1.txt"
SAP_ARRAY="s2.txt"
how can i pass this full array to a function.
here is the sample code i am using..

Hi, guys
I just wanted to sort the elements of an array ascendingly.
I know the following code does work well:
array=(13 435 8 23 100)
for i in {0..4}
do
j=$((i+1))
while ]
do
if } -le ${array} ]]
then :
else
min=${array}
${array}=${array}
${array}=$min

There are two parts to this. In the first part I need to read a list of files from a directory and split it into 4 arrays. I have done that with the following code,
# collect list of file names
STATS_INPUT_FILENAMES=($(ls './'$SET'/'$FOLD'/'*'in.txt'))
# get number of files... (8 Replies)
Hi,
I am creating filesystem for block device, but I want to pass array value one by one acording to block device count.
$tmp1 = block device count 3
$blockdevice =
So I want to first pass sdb1 alone in loop, how to take only block device seprately from $blockdevice array. (1 Reply)
I'm able to read & print an array in varaible called "filelist"
I need to pass this array variable to a function called verify() and then read and loop through the passed array inside the function.
Unfortunately it does not print the entire array from inside the funstion's loop.

MALLOC(3F)MALLOC(3F)NAME
malloc, free, falloc - memory allocator
SYNOPSIS
subroutine malloc (size, addr)
integer size, addr
subroutine free (addr)
integer addr
subroutine falloc (nelem, elsize, clean, basevec, addr, offset)
integer nelem, elsize, clean, addr, offset
DESCRIPTION
Malloc, falloc and free provide a general-purpose memory allocation package. Malloc returns in addr the address of a block of at least
size bytes beginning on an even-byte boundary.
Falloc allocates space for an array of nelem elements of size elsize and returns the address of the block in addr. It zeros the block if
clean is 1. It returns in offset an index such that the storage may be addressed as basevec(offset+1) ... basevec(offset+nelem). Falloc
gets extra bytes so that after address arithmetic, all the objects so addressed are within the block.
The argument to free is the address of a block previously allocated by malloc or falloc; this space is made available for further alloca-
tion, but its contents are left undisturbed. To free blocks allocated by falloc, use addr in calls to free, do not use basevec(offset+1).
Needless to say, grave disorder will result if the space assigned by mallocorfalloc is overrun or if some random number is handed to free.
DIAGNOSTICS
Malloc and falloc set addr to 0 if there is no available memory or if the arena has been detectably corrupted by storing outside the bounds
of a block.
The following example shows how to obtain memory and use it within a subprogram:
integer addr, work(1), offset
...
call falloc ( n, 4, 0, work, addr, offset )
do 10 i = 1, n
work(offset+i) = ...
10 continue
The next example reads in dimension information, allocates space for two arrays and two vectors, and calls subroutine doit to do the compu-
tations:
integer addr, dummy(1), offs
read *, k, l, m
indm1 = 1
indm2 = indm1 + k*l
indm3 = indm2 + l*m
indsym = indm3 + k*m
lsym = n*(n+1)/2
indv = indsym + lsym
indtot = indv + m
call falloc ( indtot, 4, 0, dummy, addr, offs )
call doit( dummy(indm1+offs), dummy(indm2+offs),
. dummy(indm3+offs), dummy(indsym+offs),
. dummy(indv +offs), m, n, lsym )
end
subroutine doit( arr1, arr2, arr3, vsym, vec, m, n, lsym )
real arr1(k,l), arr2(l,m), arr3(k,m), vsym(lsym), v2(m)
...
