NAME
cktime - display a prompt; verify and return a time of day
SYNOPSIS
cktime [ -Q ] [ -W width ] [ -f format ] [ -d default ] [ -h help ] [ -e
error ]
[ -p prompt ] [ -k pid [ -s signal ] ]
errtime [ -W width ] [ -e error ] [ -f format ]
helptime [ -W width ] [ -h help ] [ -f format ]
valtime [ -f format ] input
DESCRIPTION
cktime prompts a user and validates the response. It defines, among
other things, a prompt message whose response should be a time, text for
help and error messages, and a default value (which is returned if the
user responds with a RETURN). The user response must match the defined
format for the time of day.
All messages are limited in length to 70 characters and are formatted
automatically. Any white space used in the definition (including
newline) is stripped. The -W option cancels the automatic formatting.
When a tilde is placed at the beginning or end of a message definition,
the default text is inserted at that point, allowing both custom text and
the default text to be displayed.
If the prompt, help or error message is not defined, the default message
(as defined under NOTES) is displayed.
Three visual tool modules are linked to the cktime command. They are
errtime (which formats and displays an error message), helptime (which
formats and displays a help message), and valtime (which validates a
response). These modules should be used in conjunction with FMLI
objects. In this instance, the FMLI object defines the prompt. When
format is defined in the errtime and helptime modules, the messages
describe the expected format.
The options and arguments for this command are:
-Q Do not allow quit as a valid response.
-W Use width as the line length for prompt, help, and error messages.
-f Verify the input against format. Possible formats and their
definitions are:
%H = hour (00 - 23)
%I = hour (00 - 12)
%M = minute (00 - 59)
%p = ante meridian or post meridian
%r = time as %I:%M:%S %p

%R = time as %H:%M (the default format)
%S = seconds (00 - 59)
%T = time as %H:%M:%S
-d The default value is default. The default is not validated and so
does not have to meet any criteria.
-h The help message is help.
-e The error message is error.
-p The prompt message is prompt.
-k pid
Send process ID pid a signal if the user chooses to abort.
-s signal
When quit is chosen, send signal to the process whose pid is
specified by the -k option. If no signal is specified, use
SIGTERM.
input Input to be verified against format criteria.
EXIT CODES
0 = Successful execution
1 = EOF on input
2 = Usage error
3 = User termination (quit)
4 = Garbled format argument
NOTES
The default prompt for cktime is:
Enter a time of day [?,q]
The default error message is:
ERROR - Please enter the time of day. Format is format.
The default help message is:
Please enter the time of day. Format is format.
When the quit option is chosen (and allowed), q is returned along with
the return code 3. The valtime module does not produce any output. It
returns zero for success and non-zero for failure.
