Thread: What is the purpose of this (void)

What is the purpose of this (void) in the following code:

Code:

int functionA( structA *testresults, int test)
{
    // Some code

   (void)testresults;

   // Some code

}

This is a null expression. The use of (void) there is an attempt to avoid a compiler warning... Not really necessary (because the expression is null, but valid).

Thank you.
