path_req

path_req::absolute
path_req::relative

A convenience bundle of path and flags, with optional precondition. Paths may be a path fragment (relative to the precondition) or absolute, in which case if necessary they are made canonical and absolute in the constructor according to the current working directory.

Synopsis

struct path_req
{
  bool is_relative;        // Whether the precondition is also where this path begins. 
  boost::afio::path path;  // The filing system path to be used for this operation. 
  file_flags flags;        // The flags to be used for this operation (note they can be overriden by flags passed during dispatcher construction). 
  future precondition;     // An optional precondition for this operation 
};
