check_arg_count

Checks the number of arguments a function requires. This check does not work on macros. This check provides a way to distinguish function calls that is easier than checking the function definition.

A function that exists but is declared as func (void) will return a value of 1. A function that does not exist will return a value of 0.

check_arg_count <function-name>;
check_arg_count <function-name> { <attribute-statements> }
