6.3.10 scanf()
This function is very similar to the printf() function described earlier, except that it is used for input rath-
er than output. The function reads a string passed from an HTML form object, parses the string as spec-
ified by a template string, and sends the resulting data to the specified argument. 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, followed by a
number of arguments. Each argument corresponds to a formatting tag, which determines how the data
read from the HTML form shall be interpreted prior sending it to the destination argument.
Note:
This command cannot be used in email messages.
Syntax:
<?--#exec cmd_argument='scanf("
source"
, "
template
" [,
argument1
, ...,
argumentN
])'-->
