strtok() gives segmentation fault!!
Code:
#include<iostream.h>
#include<string>
#include<stdio.h>
int main()
{
char *cmd="delete backup backup-iso image a.iso b.iso c.iso d.iso";
char *tokenized_cmd,*sub_cmd;
sub_cmd=strstr(cmd,"image");
tokenized_cmd=strtok(sub_cmd," ");
while(tokenized_cmd != NULL)
{
tokenized_cmd=strtok(NULL," ");
if(tokenized_cmd!=NULL)
{
cout<<tokenized_cmd<<" ";
}
}
}a.iso b.iso c.iso d.iso
i.e.,whatever is there after the word "image".
but the command tokenized_cmd=strtok(cmd," ");
is throwing segmentation fault!!
Any mistakes you could find in the snippet??

pkg2du
pkg2du(1M) System Administration Commands pkg2du(1M) NAME
pkg2du - convert driver packages to Driver Update format SYNOPSIS
/usr/bin/pkg2du [-f] [-v] [-d dir] [-o iso] [-l label] [-r release] pkg [pkg ...] DESCRIPTION
The /usr/bin/pkg2du utility takes one or more packages as input and converts them to Driver Update (DU) format. If the -d option is speci- fied, the resulting DU directory tree is placed in the directory dir. If the -o option is specified, a Solaris ISO image of the DU direc- tory tree is written in the file iso. The ISO image can be burned onto CD/DVD using cdrw(1) or cdrecord(1) (not a SunOS man page) and used during Solaris installation. At least one of the -d and -o options must be specified. If both are specified, then both an ISO image and a directory tree are generated. OPTIONS
The following options are supported: -d dir Directory where the DU directory should be created. -o iso Create a Solaris ISO image of the DU directory. -f If dir/DU or iso exists, remove it without asking first. -l label Label/volume name of the ISO image (if -o option is specified). -r release Solaris release number to use. It takes the form of the return from uname -r command, for example, 5.10. If unspecified, the release number of the currently running Solaris is used. -v Verbose. Multiple -v options increase verbosity. OPERANDS
The following operands are supported: pkg [pkg...] One or more packages to be converted to DU format. EXAMPLES
Example 1 Creating a DU CD/DVD The following commands create a DU CD or DVD containing packages SUNWfoo and SUNWbar. # /usr/bin/pkg2du -r 5.10 -o my.iso SUNWfoo SUNWbar # /usr/bin/cdrw -i my.iso ATTRIBUTES
