So the output will look like this:

Im new to C, and Im having a hard time getting a random number.
In bash, I would do something similar to the following to get a random number;
#!/bin/bash
seed1=$RANDOM
seed2=$RANDOM
seed3=$RANDOM
SEED=`expr $seed1 * $seed2 / $seed3`
echo ${SEED%.*}
Now, in online examples... (4 Replies)
Hi All,
I have extracted some report from database for few activities done.
Now I have a requirement to add some random time(In range of 10-35) in front of each activity.

Hi,
How can I generate a string of random characters (alpha+numeric) of a particular length ?
For e.g. for
n=5, output = 'kasjf'
n=10, output = 'hedbcd902k'
Also, please let me know if random (valid) dates could also be generated.
Thanks (7 Replies)
Hi Guys and gals...
As you know I am getting to grips with POSIX and hit this stumbling block.
Generating two random numbers 0 to 255 POSIXly. Speed in not important hence the 'sleep 1' command.
I have done a demo that works, but it sure is ugly! Is there a better way?

wsreg_get_instance
wsreg_set_instance(3WSREG) Product Install Registry Library Functions wsreg_set_instance(3WSREG)NAME
wsreg_set_instance, wsreg_get_instance - set or get the instance of a component
SYNOPSIS
cc [flag ...] file ...-lwsreg [library ...]
#include <wsreg.h>
int wsreg_set_instance(Wsreg_component *comp, int instance);
int wsreg_get_instance(Wsreg_component *comp);
DESCRIPTION
The wsreg_set_instance() function sets the instance number specified by instance of the component specified by comp. The instance number
and uuid are used to uniquely identify any component in the product install registry.
The wsreg_get_instance() function determines the instance number associated with the component specified by comp.
RETURN VALUES
The wsreg_set_instance() function returns a non-zero value if the instance was set correctly; otherwise 0 is returned.
The wsreg_get_instance() function returns the instance number associated with the specified component.
EXAMPLES
Example 1: Get the instance value of a registered component.
The following example demonstrates how how to get the instance value of a registered component.
#include <fcntl.h>
#include <wsreg.h>
int main (int argc, char **argv)
{
char *uuid = "d6cf2869-1dd1-11b2-9fcb-080020b69971";
Wsreg_component *comp = NULL;
/* Initialize the registry */
wsreg_initialize(WSREG_INIT_NORMAL, NULL);
if (!wsreg_can_access_registry(O_RDWR)) {
printf("No permission to modify the registry.
");
return 1;
}
/* Create a component */
comp = wsreg_create_component(uuid);
wsreg_set_unique_name(comp, "wsreg_example_1");
wsreg_set_version(comp, "1.0");
wsreg_add_display_name(comp, "en", "Example 1 component");
wsreg_set_type(comp, WSREG_COMPONENT);
wsreg_set_location(comp, "/usr/local/example1_component");
/* Register */
wsreg_register(comp);
printf("Instance %d was assigned
", wsreg_get_instance(comp));
wsreg_free_component(comp);
return 0;
}
USAGE
Upon component registration with the wsreg_register(3WSREG) function, the instance number is set automatically. The instance number of 0
(the default) indicates to the wsreg_register() function that an instance number should be looked up and assigned during registration. If
a component with the same uuid and location is already registered in the product install registry, that component's instance number will be
used during registration.
After registration of a component, the wsreg_get_instance() function can be used to determine what instance value was assigned.
