CKINT(1) User Commands CKINT(1)


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


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


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.


The following options are supported:

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

-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.

Specifies that quit will not be allowed as a valid

-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.


The following operand is supported:

Input to be verified against base criterion.


The following exit values are returned:

Successful execution.

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

User termination (quit).




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.
