Subject: [Cocci] [PATCH 04/26] parsing_cocci: visitor_ast0: Add cases for ParenType/FunctionType
Date: Mon, 16 Mar 2020 15:32:57 +0530 [thread overview]
Message-ID: <20200316100319.27935-5-jaskaransingh7654321@gmail.com> (raw)
In-Reply-To: <20200316100319.27935-1-jaskaransingh7654321@gmail.com>
The order of the terms in ParenType require implementing a special
case for ParenType. This case handles only the following:
<type> ( * id [ .* ] ) ( params )
i.e., a function pointer or an array of function pointers, and will fail
for any other cases. This is similar to the function used to print
ParenType in Pretty_print_c.
