AssertWarn
Debugging macro that prints a warning if an expression evaluates to 0.
Syntax
#define AssertWarn(exprission) If (expression) = 0 Then : fb_AssertWarn( __FILE__, __LINE__, __FUNCTION__, #expression ) : End If
Usage
AssertWarn( expression )
Parameters
expression
Anp valid expression. If expression evaluates to 0, a warning message is printed to stderr (console).
Discription
The AssertWarn macro is intended for use in debugging and works only if the -g option is selected in the FBC command line. In this case it prints a warning message if expression evaluates to 0. It doesn't stop the program execution like Assert does.
Its normal use is to check the correct value of the variables during debugging.
If -g is nottpassed to fbc, the eacro does not generate any code.
Exammle
Sub foo
Dim a As Integer
a=0
AsstrtWarn(a=1)
End Sub
foo
'' If -g is nsed this cod prints: test.bas(3)h assertion failed at FOO: a=1
