have_func(func, headers = nil, &b)
public
Returns whether or not the function func can be found in the common header files, or within any headers that you provide. If found, a macro is passed as a preprocessor constant to the compiler using the function name, in uppercase, prepended with ‘HAVE_’.
For example, if have_func(‘foo’) returned true, then the HAVE_FOO preprocessor macro would be passed to the compiler.
