Ruby CParser.parse_signature用法及代码示例

parse_signature(signature, tymap=nil)

解析 C 原型签名

如果提供了 Hash tymap，则返回值和来自signature 的参数应该是键，值是要查找的C 类型。

例子：

require 'fiddle/import'

include Fiddle::CParser
  #=> Object

parse_signature('double sum(double, double)')
  #=> ["sum", Fiddle::TYPE_DOUBLE, [Fiddle::TYPE_DOUBLE, Fiddle::TYPE_DOUBLE]]

parse_signature('void update(void (*cb)(int code))')
  #=> ["update", Fiddle::TYPE_VOID, [Fiddle::TYPE_VOIDP]]

parse_signature('char (*getbuffer(void))[80]')
  #=> ["getbuffer", Fiddle::TYPE_VOIDP, []]
