Is there a way to get the command line arguments.
I am using getopt(3) but if the arguments are more than one for a particular option than it just ignores the second argument. For eg
./a.out -x abc def
now abd will be got with -x using getopt "( x : )" and string abc\0def will get stored... (7 Replies)

Hi all,
How many arguments can we pass while testing a prgm at command line..
I encountered an issue while passing 10 arguments.
For $10 its taking argument passed for $1 followed by 'zero'.
can we pass more than 9 arguments /Is there any other way.
Thanks,

random_harvest
RANDOM_HARVEST(9) BSD Kernel Developer's Manual RANDOM_HARVEST(9)NAME
random_harvest -- gather entropy from the kernel for the entropy device
SYNOPSIS
#include <sys/types.h>
#include <sys/random.h>
void
random_harvest(void *entropy, u_int size, u_int bits, u_int frac, enum esource source);
DESCRIPTION
The random_harvest() function is used by device drivers and other kernel processes to pass data that is considered (at least partially) sto-
chastic to the entropy device.
The caller should pass a pointer (to no more than 16 bytes) of the ``random'' data in entropy. The argument size contains the number of
bytes pointed to. The caller should very conservatively estimate the number of random bits in the sample, and pass this in bits or frac. If
the estimated number of bits per sample is an integer, then bits is used, and frac is 0. Otherwise, for low-entropy samples, ``fractional''
entropy can be supplied in frac. (This is considered to be frac / 1024 bits of entropy.) The source is chosen from RANDOM_WRITE,
RANDOM_KEYBOARD, RANDOM_MOUSE, RANDOM_NET and RANDOM_INTERRUPT, and is used to indicate the source of the entropy.
Interrupt harvesting has been simplified for the kernel programmer. If a device driver registers an interrupt handler with BUS_SETUP_INTR(9)
or bus_setup_intr(9), then it is only necessary to include the INTR_ENTROPY bit in the flags argument to have that interrupt source be used
for entropy harvesting.
