9.3.10 scanf()

This function is very similar to the printf() function described earlier, except that it is used for in-

put rather than output. The function reads a string passed from an HTML form object, parses

the string as specified by a template string, and sends the resulting data to the specified argu-

ment. The formatting syntax used is similar to that of the standard C-function scanf().

The function accepts a source, a template string containing zero or more formatting tags, fol-

lowed by a number of arguments. Each argument corresponds to a formatting tag, which deter-

mines how the data read from the HTML form shall be interpreted prior sending it to the

destination argument.

This command cannot be used in e-mail messages.

Syntax:

<?--#exec cmd_argument='scanf("source", "template" [,

argument1, ..., argumentN])'-->

source

Name of the HTML form object from which the string shall be extracted.

template: Template which specifies how to parse and interpret the data. May contain any number

of formatting tags which determine the conversion prior to sending the data to subse-

quent arguments. The number of formatting tags must match the number of argu-

ments; if not, the result is undefined.

See section “Formatting Tags” below for more information.

argument:

Destination argument(s) specifying where to send the interpreted data. The number of

arguments must match the number of formatting tags; if not, the result is undefined.

At the time of writing, the only allowed argument is ABCCMessage().
