NAME
cktime, errtime, helptime, valtime - display a prompt; verify and
return a time of day
SYNOPSIS
/usr/bin/cktime [-Q] [-W width] [-f format] [-d default] [-h help]
[-e error] [-p prompt] [-k pid [-s signal]]
/usr/sadm/bin/errtime [-W] [-e error] [-f format]
/usr/sadm/bin/helptime [-W] [-h help] [-f format]
/usr/sadm/bin/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 will be
returned if the user responds with a carriage 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 new-
line) is stripped. The -W option cancels the automatic formatting.
When a tilde is placed at the beginning or end of a message defini-
tion, the default text will be 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 mes-
sage (as defined under NOTES) will be 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 FML
objects. In this instance, the FML object defines the prompt. When
format is defined in the errtime and helptime modules, the messages
will describe the expected format.

OPTIONS
The options and arguments for this command are:
-Q Specifies that quit will not be allowed as a valid response.
-W Specifies that prompt, help and error messages will be format-
ted to a line length of width.
-f Specifies the format against which the input will be verified.
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 Defines the default value as default. The default is not vali-
dated and so does not have to meet any criteria.
-h Defines the help messages as help.
-e Defines the error message as error.
-p Defines the prompt message as prompt.
-k Specifies that process ID pid is to be sent a signal if the
user chooses to abort.
-s Specifies that the process ID pid defined with the -k option is
to be sent signal signal when quit is chosen. If no signal is
specified, SIGTERM is used.
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
