Appendix 2
The arguments that can be passed to the SSI function printf are:
Argument
InReadSByte(offset)
InReadUByte(offset)
InReadSWord(offset)
InReadUWord(offset)
InReadSLong(offset)
InReadULong(offset)
InReadString(offset)
InReadFloat(offset)
OutReadSByte(offset)
OutReadUByte(offset)
OutReadSWord(offset)
OutReadUWord(offset)
OutReadSLong(offset)
OutReadULong(offset)
OutReadString(offset)
OutReadFloat(offset)
scanf
Syntax:
<?--#exec cmd_argument='scanf( "ObjName", "format", Arg1, ..., ArgN), ErrVal1, ..., ErrvalN'-->
This SSI function reads a string passed from an object in a HTML form, interprets the
string according to the specification in format, and stores the result in the OUT area
according to the passed arguments. The formatting of the string is equal to the standard C
function call scanf()
ObjName
format
Arg1 - ArgN
ErrVal1 -ErrValN
