Module Errorloc

module Errorloc: sig .. end
The module stores the current file,line, and working directory in a hidden internal state, modified by the three following functions.

val newline : unit -> unit
Call this function to announce a new line
val currentLoc : unit -> Cil_datatype.Location.t
val setCurrentWorkingDirectory : string -> unit
This function is used especially when the preprocessor has generated linemarkers in the output that let us know the current working directory at the time of preprocessing (option -fworking-directory for GNU CPP).
val setCurrentFile : string -> unit
val setCurrentLine : int -> unit
val startParsing : string -> Lexing.lexbuf
Call this function to start parsing.
val finishParsing : unit -> unit
Call this function to finish parsing and close the input channel
val pp_context_from_file : ?ctx:int -> ?start_line:int -> Format.formatter -> Filepath.position -> unit
prints the line identified by the position, together with ctx lines of context before and after. ctx defaults to 2. If start_line is specified, then all lines between start_line and pos.pos_lnum are considered part of the error.
val parse_error : ?source:Filepath.position ->
('a, Format.formatter, unit, 'b) Pervasives.format4 -> 'a
Parse errors are usually fatal, but their reporting is sometimes delayed until the end of the current parsing phase. Functions that intend to ultimately fail should call Errorloc.clear_errors when they start, and check Errorloc.had_errors when they end.
val had_errors : unit -> bool
Has an error been raised since the last call to Errorloc.clear_errors?
val clear_errors : unit -> unit
