Pointers from each instantiated --- package are then used to reference arrays of the appropriate --- element type. The subprograms under test are used to determine the --- length, and to copy, either portions or the entire content of the --- arrays. The results of these operations are then compared against --- expected results. --- --- The propagation of Dereference_Error is checked for when either --- of the two procedures is supplied with a null Pointer parameter. --- --- This test assumes that the following characters are all included --- in the implementation defined type Interfaces.C.char: --- ' ', and 'a'..'z'. --- --- APPLICABILITY CRITERIA: --- This test is applicable to all implementations that provide --- packages Interfaces.C, Interfaces.C.Strings, and --- Interfaces.C.Pointers. If an implementation provides these packages, --- this test must compile, execute, and report "PASSED". --- --- --- CHANGE HISTORY: --- 01 Feb 96 SAIC Initial release for 2.1 --- 13 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. --- 26 Oct 96 SAIC Incorporated reviewer comments. --- 26 Feb 97 PWB.CTA Moved code using null pointer to avoid errors ---! - -with Report; -with Ada.Exceptions; -with Interfaces.C; -- N/A => ERROR -with Interfaces.C.Pointers; -- N/A => ERROR -with Interfaces.C.Strings; -- N/A => ERROR - -procedure CXB3016 is -begin - - Report.Test ("CXB3016", "Check that subprograms Virtual_Length, " & - "Copy_Terminated_Array, and Copy_Array " & - "produce correct results"); - - Test_Block: - declare - - use Ada.Exceptions; - use Interfaces.C.Strings; - - use type Interfaces.C.char, - Interfaces.C.char_array, - Interfaces.C.ptrdiff_t, - Interfaces.C.short, - Interfaces.C.size_t; - - TC_char : Interfaces.C.char := 'a'; - TC_ptrdiff_t : Interfaces.C.ptrdiff_t; - TC_Short : Interfaces.C.short := 0; - Min_Array_Size : Interfaces.C.size_t := 0; - Max_Array_Size : Interfaces.C.size_t := 20; - Short_Terminator : Interfaces.C.short := Interfaces.C.short'Last; - Alphabet : constant String := "abcdefghijklmnopqrstuvwxyz"; - Blank_String : constant String := " "; - - type Short_Array_Type is - array (Interfaces.C.size_t range <>) of aliased Interfaces.C.short; - - Ch_Array : Interfaces.C.char_array - (0..Interfaces.C.size_t(Alphabet'Length)) := - Interfaces.C.To_C(Alphabet, True); - - TC_Ch_Array : Interfaces.C.char_array - (0..Interfaces.C.size_t(Blank_String'Length)) := - Interfaces.C.To_C(Blank_String, True); - - Short_Array : Short_Array_Type(Min_Array_Size..Max_Array_Size); - TC_Short_Array : Short_Array_Type(Min_Array_Size..Max_Array_Size); - - - package Char_Pointers is new - Interfaces.C.Pointers (Index => Interfaces.C.size_t, - Element => Interfaces.C.char, - Element_Array => Interfaces.C.char_array, - Default_Terminator => Interfaces.C.nul); - - package Short_Pointers is new - Interfaces.C.Pointers (Index => Interfaces.C.size_t, - Element => Interfaces.C.short, - Element_Array => Short_Array_Type, - Default_Terminator => Short_Terminator); - - use Short_Pointers, Char_Pointers; - - Short_Ptr : Short_Pointers.Pointer := Short_Array(0)'Access; - TC_Short_Ptr : Short_Pointers.Pointer := TC_Short_Array(0)'Access; - Char_Ptr : Char_Pointers.Pointer := Ch_Array(0)'Access; - TC_Char_Ptr : Char_Pointers.Pointer := TC_Ch_Array(0)'Access; - - begin - - -- Provide initial values for the array that holds short int values. - - for i in Min_Array_Size..Max_Array_Size loop - Short_Array(i) := Interfaces.C.short(i); - TC_Short_Array(i) := 100; - end loop; - - -- Set the final element of the short array object to be the "terminator" - -- element used in the instantiation above. - - Short_Array(Max_Array_Size) := Short_Terminator; - - -- Check starting pointer positions. - - if Short_Ptr.all /= 0 or - Char_Ptr.all /= Ch_Array(0) - then - Report.Failed("Incorrect initial value for the first " & - "Char_Array or Short_Array values"); - end if; - - - - -- Check that function Virtual_Length returns the number of elements - -- in the array referenced by the Pointer parameter Ref, up to (but - -- not including) the (first) instance of the element specified in - -- the Terminator parameter. - - TC_char := 'j'; - - TC_ptrdiff_t := Char_Pointers.Virtual_Length(Ref => Char_Ptr, - Terminator => TC_char); - if TC_ptrdiff_t /= 9 then - Report.Failed("Incorrect result from function Virtual_Length " & - "with Char_ptr parameter - 1"); - end if; - - TC_char := Interfaces.C.nul; - - TC_ptrdiff_t := Char_Pointers.Virtual_Length(Char_Ptr, - Terminator => TC_char); - if TC_ptrdiff_t /= Interfaces.C.ptrdiff_t(Alphabet'Length) then - Report.Failed("Incorrect result from function Virtual_Length " & - "with Char_ptr parameter - 2"); - end if; - - TC_Short := 10; - - TC_ptrdiff_t := Short_Pointers.Virtual_Length(Short_Ptr, TC_Short); - - if TC_ptrdiff_t /= 10 then - Report.Failed("Incorrect result from function Virtual_Length " & - "with Short_ptr parameter - 1"); - end if; - - -- Replace an element of the Short_Array with the element used as the - -- terminator of the entire array; now there are two occurrences of the - -- terminator element in the array.
