---------------------------
-- File Name Conventions --
---------------------------
-- GNAT requires that there be a one to one correspondence between source
-- file names (as used in the Osint package interface) and unit names as
-- defined by the Uname package. This correspondence is defined by the
-- two subprograms defined here in the Fname package.
-- For full rules of file naming, see GNAT User's Guide. Note that the
-- naming rules are affected by the presence of Source_File_Name pragmas
-- that have been previously processed.
-- Note that the file name does *not* include the directory name. The
-- management of directories is provided by Osint, and full file names
-- are used only for error message purposes within GNAT itself.

function Is_Predefined_File_Name

-- This function determines if the given file name (which must be a simple
-- file name with no directory information) is the file name for one of the
-- predefined library units (i.e. part of the Ada, System, or Interface
-- hierarchies). Note that units in the GNAT hierarchy are not considered
-- predefined (see Is_Internal_File_Name below). On return, Name_Buffer
-- contains the file name. The Renamings_Included parameter indicates
-- whether annex J renamings such as Text_IO are to be considered as
-- predefined. If Renamings_Included is True, then Text_IO will return
-- True, otherwise only children of Ada, Interfaces and System return True.
