19.6.101 Printf (Create and Store formatted string)
Syntax
Printf (FormatString, FormatArgs) => String
Arguments
Printf is a macro that converts the evaluated FormatString into a series of string Concatenate
operations, storing the result in the Debug object.
FormatString is a string literal which may contain one or more uses of the format specifier, %o, to
indicate locations in the string where an object may be inserted. %o is the only format specifier
supported since the resulting object is a string and type conversion is handled automatically by
Concatenate.
FormatArgs is a comma separated list of Named Objects, Locals, or Args that can be evaluated to a
string. Each argument is added to the FormatString using the Concatenate operation at the location
specified by %o in order of appearance.
Description
The Printf macro converts a format string into a series of cascading string Concatenate operations,
and stores the result in the Debug object
Example
The following ASL example uses Printf to write a formatted string with the values of Arg0, Arg1,
Arg2, and Arg3 to the Debug Object.
Printf ("%o: Unexpected value for %o, %o at line %o",
Arg0, Arg1, Arg2, Arg3)
This Printf macro expression evaluates to the following ASL operation.
