27 -- This child package contains the routines to translate a unit name to
28 -- a file name taking into account Source_File_Name pragmas. It also
29 -- contains the auxiliary routines used to record data from the pragmas.
31 -- Note: the reason we split this into a child unit is that the routines
32 -- for unit name translation have a significant number of additional
33 -- dependencies, including osint, and hence sdefault. There are a number
34 -- of tools that use utility subprograms in the Fname parent, but do not
35 -- need the functionality in this child package (and certainly do not want
36 -- to deal with the extra dependencies).

50 -- This function returns the file name that corresponds to a given unit
51 -- name, Uname. The Subunit parameter is set True for subunits, and
52 -- false for all other kinds of units. The caller is responsible for
53 -- ensuring that the unit name meets the requirements given in package
54 -- Uname and described above.
55 -- When May_Fail is True, if the file cannot be found, this function
56 -- returns No_File. When it is False, if the file cannot be found,

62 -- package body is elaborated, so an explicit call to Initialize is

70 -- Returns the file name that corresponds to the spec of a given unit
71 -- name. The unit name here is not encoded as a Unit_Name_Type, but is
72 -- rather just a normal form name in lower case, e.g. "xyz.def".

79 procedure Set_File_Name (U : Unit_Name_Type; F : File_Name_Type);
80 -- Make association between given unit name, U, and the given file name,
81 -- F. This is the routine called to process a Source_File_Name pragma.
83 procedure Set_File_Name_Pattern
88 -- This is called to process a Source_File_Name pragma whose first
89 -- argument is a file name pattern string. Pat is this pattern string,
90 -- which contains an asterisk to correspond to the unit. Typ is one of
91 -- 'b'/'s'/'u' for body/spec/subunit, Dot is the separator string
92 -- for child/subunit names, and Cas is one of Lower/Upper/Mixed
93 -- indicating the required case for the file name.
