|
|
-- 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.
