[I have a DLL which contains simple functions

function1 is just returning a char value

function2 returns a Long value

function3 returns a int value

function4 returns a double value

function5 returns a float value

but when I assign a 4test variable by calling all above functions or printing the returned value it creates a problem.

Problem:

1. Not able to return the correct "char" value from dll function. it gives garbage. same problem is with function returning float . working fine for the function returning int,double.DLL is loaded properly. Using "SilkTest 6.5 International", windows-xp. Dll was created in .NET framework . Also the functions are wrapped into "C" wrapper

Above all function gives correct values when call in a .NET framework.]

Used proper SilkTest DataType ie. String corresponding to C Char type But this time Agents crashes giving error *** Error: The Agent has abnormally exited when Aborted and silk test hangs on the statement calling Dll function returning char .

Please see the sample code

[+] dll "C:partnerTEST70FrameXPressVishnu1.dll"

[ ] String ReturnChar()

[ ] float ReturnFloat()

[ ] double ReturnDouble()

[ ] long ReturnLong()

[ ] int ReturnInt()

[+] testcase DllTest()

[ String str=ReturnChar()

// hangs for ever at above statement and agent crashes

[ ] Print(ReturnInt())

[ ] Print(ReturnChar())

[ ] Print(ReturnFloat())

[ ] Print(ReturnDouble())

[ ] Print(ReturnLong())

in Dll definition of ReturnChar()

Char ReturnChar()

{

Char a='h' ;

return a;

}
