Hi scottn,
I am looking into a table if there is any update value then will create the file with that value. There may be more than one value. function1 will pick the last value and delete it. So if a value is picked by function1 will write to the file. And if file created then need to call function2 which processed the file. wait till it fails/success, again function1 will kick off look on the other updated value. And if no value will sleep and again look after one minute.
Thanks,
Satya

Production C code compiled without the dash-g option is running, and seems to be in an infinite loop. Is there a way to tell? Is there a diagnostic tool that will report what objects or what lines of code or even what functions are being executed?
Or is my best option to kill it with a dump?

sleep(1) General Commands Manual sleep(1)
NAME
sleep - Suspends execution for at least the specified time
SYNOPSIS
sleep seconds
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
sleep: XCU5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
OPTIONS
None
OPERANDS
Non-negative integer specifying the number of seconds for which execution is to be suspended.
DESCRIPTION
The sleep command suspends execution of a process for at least the interval specified by seconds, which can range from 0 to 2,147,483,647
seconds. Depending on system activity, the actual time of suspension may be longer. See the sleep(3) reference page.
[Tru64 UNIX] seconds can be entered as a non-negative decimal, octal, or hexadecimal value.
NOTES
If sleep receives a SIGALARM signal before process execution has resumed, sleep takes one of the following actions: Terminates normally
with a 0 (zero) exit status. (See the sleep(3) reference page for more information.) Ignores the signal Performs default processing
EXIT STATUS
The following exit values are returned: Execution was successfully suspended for at least the requested time, or a SIGALARM signal was
received. An error occurred.
EXAMPLES
To display a message at 4-minute intervals for 20 minutes, create a shell script called remind containing the following:
for i do sleep 240; echo $i sleep 240; echo $i sleep 240; echo $i sleep 240; echo $i sleep 240; echo $i done
To display the message Try calling NHK at 4-minute intervals, enter: remind 'Try calling NHK' To run a command at regular intervals,
create a shell script containing the following:
while true do
date
sleep 60 done
This displays the date and time once a minute. To execute a command after a specified interval, enter the following; (sleep 3600;
echo Time's up) &
This displays the message "Time's up" after one hour.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of sleep: Provides a default value for the internationalization variables that are
unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari-
ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value,
overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes
of text data as characters (for example, single-byte as opposed to multibyte characters in arguments). Determines the locale for the for-
mat and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the processing of
LC_MESSAGES.
