Controls the suppression of warnings for variables and parameters that aren't referenced in a function.

This pragma is compatible with the following platform targets:

68K

PowerPC

NEC V800

Intel x86

MIPS

Embedded 68K

This pragma suppresses the compile time warnings for the unused variables and parameters specified in its argument list. You can use this pragma only within a function body, and the listed variables must be within the function's scope. You cannot use this pragma with functions defined within a class definition or with template functions. For example:

#pragma warn_unusedvar on
#pragma warn_unusedarg on

static void ff(int a)
{
  int b;
#pragma unused(a,b)  // Compiler won't complain 
                     // that a and b are unused
  // . . . 
}

This pragma does not correspond to an option in any settings panel.
