Calling random seed repeatedly is sort of overdoing it - or, in your case, even counterproductive. Do it once at program startup - if at all necessary as the compiler / interpreter may do it for you.
I know you are compiling a (C) program. Just as a hint, man awk explicitly says
Quote:
Srand(expr) is useful for repeating pseudo random sequences.
Although you are calling srand() with a sort of random parameter, the current system epoch time, the execution will be that fast epoch seconds will not change - that's why you lose the random effect.
hi all,
i have been trying to get a script working that can take in more than one option using getopt. But for some reason, even when i type in a covered option, it skips directly to my error message of "no match." Any ideas of what might be wrong?

devswmgr
devswmgr(8) System Manager's Manual devswmgr(8)NAME
devswmgr - utility to manage the device switch database
SYNOPSIS
/sbin/devswmgr [-option [parameter]]
OPTIONS
Displays the following information about the device switch database:
Whether a device switch database was read from the primary file or from a backup file
The number of entries that are in the device switch table Displays the major numbers that have been reserved by all drivers, a named
driver, or an instance of a named driver.
A driver that requires more than one entry in the device switch table uses a unique instance number to reference each of its device
switch table entries. Displays help for the devswmgr command. Releases all the major numbers for a device driver if just the
driver name is specified. Releases one major number for a device driver if the NAME and the INSTANCENUM of the driver are speci-
fied.
DESCRIPTION
The devswmgr command helps you manage the device switch table by displaying information about the devices drivers in the table.
You can also use the command to release device switch table entries. Typically, you release the entries for a driver after you have
unloaded the driver and do not plan to reload it later. Releasing the entries frees them for use by other device drivers.
EXAMPLES
The following example shows that a device switch table was loaded from the primary device and that there are 70 entries in it: %
/sbin/devswmgr -display Device switch information
device switch database read from primary file
device switch table has 70 entries The following example shows the major numbers in the device switch table that have been reserved for
the driver named cam_disk: % /sbin/devswmgr -getnum driver=cam_disk
Device switch reservation list
(*=entry in use)
driver name instance major
--------------------------------------------
cam_disk 1 8*
FILES
The file that manages the device switch databases The primary device switch database file The backup device switch database file
