Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v1_9_3_392) is shown here.

have_type(type, headers = nil, opt = "", &b)
public

Returns whether or not the static type type is defined. You may optionally pass additional headers to check against in addition to the common header files.

You may also pass additional flags to opt which are then passed along to the compiler.

If found, a macro is passed as a preprocessor constant to the compiler using the type name, in uppercase, prepended with ‘HAVE_TYPE_’.

For example, if have_type(‘foo’) returned true, then the HAVE_TYPE_FOO preprocessor macro would be passed to the compiler.
