NAME

ckint, errint, helpint, valint - display a prompt; verify and return
an integer value

SYNOPSIS

ckint [-Q] [-W width] [-b base] [-d default] [-h help]
[-e error] [-p prompt] [-k pid [-s signal]]


/usr/sadm/bin/errint [-W width] [-b base] [-e error]


/usr/sadm/bin/helpint [-W width] [-b base] [-h help]


/usr/sadm/bin/valint [-b base] input

DESCRIPTION

The ckint utility prompts a user, then validates the response. It
defines, among other things, a prompt message whose response should
be an integer, text for help and error messages, and a default value
(which will be returned if the user responds with a carriage return).


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 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
message (as defined under NOTES) will be displayed.


Three visual tool modules are linked to the ckint command. They are
errint (which formats and displays an error message), helpint (which
formats and displays a help message), and valint (which validates a
response). These modules should be used in conjunction with FML
objects. In this instance, the FML object defines the prompt. When
base is defined in the errint and helpint modules, the messages will
include the expected base of the input.

OPTIONS

The following options are supported:

-b base
Defines the base for input. Must be 2 to 36, default
is 10.


-d default
Defines the default value as default. The default is
not validated and so does not have to meet any
criteria.


-e error
Defines the error message as error.


-h help
Defines the help messages as help.


-k pid
Specifies that process ID pid is to be sent a signal if
the user chooses to abort.


-p prompt
Defines the prompt message as prompt.


-Q
Specifies that quit will not be allowed as a valid
response.


-s signal
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.


-W width
Specifies that prompt, help and error messages will be
formatted to a line length of width.

OPERANDS

The following operand is supported:

input
Input to be verified against base criterion.

EXIT STATUS

The following exit values are returned:

0
Successful execution.


1
EOF on input, or negative width on -W option, or usage error.


3
User termination (quit).

NOTES

The default base 10 prompt for ckint is:

Enter an integer [?,q]:


The default base 10 error message is:

ERROR - Please enter an integer.


The default base 10 help message is:

Please enter an integer.


The messages are changed from "integer" to "base base integer" if the
base is set to a number other than 10.


When the quit option is chosen (and allowed), q is returned along
with the return code 3. The valint module will not produce any
output. It returns 0 for success and non-zero for failure.
