This code is to print out the program name and arguments list one by one:
I understand it is about pointer and pointer address of the array. Can somebody explain to me why line 7 should not be as :
I thought *argv[iCount] is the correct way as argv[iCount] is one of the array members address, not the content of the pointer pointing to. But my understanding is wrong! What did I miss? Thanks a lot!
say I have a IP address which is 10.0.0.12, and subnet mask is 255.255.255.240, what is the network address and what is the broadcast address which host lives on?
And could you explain how to get the answer?
thanx in advance! (7 Replies)

How do I get a pointer to any 32 bit address on my hard drive, in which I then could read that memory or write to that memory address?
And, while the subject is on, how do get a 32 bit pointer in RAM also, in which I can do the same?
I'm using C and Objective-C with gcc on an iBook G4.

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it:
(1) one is to pass a pointer-to-pointer parameter, like:
int my_malloc(int size, char **pmem)
{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)
Trying to do a ksh script that needs to list all ip address between ip address a and b ..
ie.
Ip address A=192.168.1.200
Ip address B=192.168.2.15
So the subnet changes from 1 to 2 but I want to list all possible ip addresses between the 2..

pvm_start_pvmd
START_PVMD(3PVM) PVM Version 3.4 START_PVMD(3PVM)NAME
pvm_start_pvmd - Starts new PVM daemon.
SYNOPSIS
C int info = pvm_start_pvmd( int argc, char **argv, int block )
Fortran call pvmfstartpvmd( args, block, info )
PARAMETERS
argc Number of arguments in argv.
argv An array of arguments to the executable.
args A character string containing the arguments to the executable.
args A character string containing the arguments to the executable.
block Integer specifying whether to block until startup of all hosts complete or return immediately.
info Integer returning the error code.
DESCRIPTION
The routine pvm_start_pvmd starts up a pvmd3 process, the master of a new virtual machine. It returns as soon as the pvmd is started and
ready for work. If the block parameter is nonzero and a hostfile is passed to the pvmd as a parameter, it returns when all hosts marked to
start have been added. pvm_start_pvmd returns zero on success.
If PVM is compiled to allow running more than one pvmd per host, a task calling pvm_start_pvmd before any other pvm functions will connect
to the pvmd that it starts. pvm_start_pvmd sets environment variable PVMSOCK to the address printed by the pvmd as it starts up.
EXAMPLES
C:
static char *argv[] = {
"-d41",
"/u/jones/pvmd_hosts",
};
argc = 2
info = pvm_start_pvmd( argc, argv, block );
Fortran:
CALL PVMFSTART_PVMD( '-d41 /u/jones/pvmd_hosts', BLOCK, INFO )
EXAMPLES
C:
static char *argv[] = {
"-d41",
"/u/jones/pvmd_hosts",
};
argc = 2
info = pvm_start_pvmd( argc, argv, block );
Fortran:
CALL PVMFSTART_PVMD( '-d41 /u/jones/pvmd_hosts', BLOCK, INFO )
ERRORS
The following error conditions can be returned
PvmDupHost
A pvmd is already running.
PvmSysErr
The local pvmd is not responding.
