| -- This package contains the low level, operating system routines used only |
| -- in the GNAT binder for command line processing and file input output. |
| |
| package Osint.B is |
| |
| procedure Record_Time_From_Last_Bind; |
| -- Trigger the computing of the time from the last bind of the same |
| -- program. |
| |
| function More_Lib_Files return Boolean; |
| -- Indicates whether more library information files remain to be processed. |
| -- Returns False right away if no source files, or if all source files |
| -- have been processed. |
| |
| function Next_Main_Lib_File return File_Name_Type; |
| -- This function returns the name of the next library info file specified |
| -- on the command line. 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. |
