It is an error to call Next_Main_Lib_File if no -- more library information files exist (i.e. Next_Main_Lib_File may be -- called only if a previous call to More_Lib_Files returned True). This -- name is the simple name, excluding any directory information. function Time_From_Last_Bind return Nat; -- This function give an approximate number of minute from the last bind. -- It bases its computation on file stamp and therefore does gibe not -- any meaningful result before the new output binder file is written. -- So it returns Nat'last if: -- -- - it is the first bind of this specific program -- - Record_Time_From_Last_Bind was not Called first -- - Close_Binder_Output was not called first -- -- otherwise it returns the number of minutes from the last bind. The -- computation does not try to be completely accurate and in particular -- does not take leap years into account. ------------------- -- Binder Output -- ------------------- -- These routines are used by the binder to generate the C source file -- containing the binder output. The format of this file is described -- in the package Bindfmt. procedure Create_Binder_Output (Output_File_Name : String; Typ : Character; Bfile : out Name_Id); -- Creates the binder output file. Typ is one of -- -- 'c' create output file for case of generating C -- 'b' create body file for case of generating Ada -- 's' create spec file for case of generating Ada -- -- If Output_File_Name is null, then a default name is used based on -- the name of the most recently accessed main source file name. If -- Output_File_Name is non-null then it is the full path name of the -- file to be output (in the case of Ada, it must have an extension -- of adb, and the spec file is created by changing the last character -- from b to s. On return, Bfile also contains the Name_Id for the -- generated file name. procedure Write_Binder_Info (Info : String); -- Writes the contents of the referenced string to the binder output file -- created by a previous call to Create_Binder_Output. Info represents a -- single line in the file, but does not contain any line termination -- characters. The implementation of Write_Binder_Info is responsible -- for adding necessary end of line and end of file control characters -- as required by the operating system. procedure Close_Binder_Output; -- Closes the file created by Create_Binder_Output, flushing any -- buffers etc from writes by Write_Binder_Info. end Osint.B;
