Macro Definition Documentation

◆ DistiAssert

#define DistiAssert (   exp)    (void)( ( exp ) || ( ::disti::DistiAssertRelease( # exp, __FILE__, __LINE__ ), 0 ) )

If a callback is registered, that function is invoked when an assertion fails (exp is false). If the callback is null, when the assertion fails, DistiAssert will popup a messagebox allowing the user to Abort, Retry(Debug) or Ignore the error. Retry will cause a User breakpoint on the error, Abort will throw a DistiException describing the error, and Ignore does nothing. At present, the function does the same thing in debug and release modes.

Note
This function is deprecated; Use GLS_ASSERT or GLS_VERIFY instead.

◆ GLS_ASSERT

#define GLS_ASSERT (   exp)
Value:
do \
{ \
(void)( ( exp ) || ( ::disti::GlsAssert( #exp, __FILE__, __LINE__ ), 0 ) ); \
} while( 0 )
void GlsAssert(const char *expression, const char *filename, unsigned int lineNumber)

In builds where GLS_DEBUG is defined OR where NDEBUG is not defined, this macro has the following behavior:

  1. If a callback is registered with SetGlsAssertHandler(), that handler is invoked when an assertion fails (exp is false).
  2. If no handler is registered and the assertion fails, on Windows GLS_ASSERT will popup a message box allowing the user to Abort, Retry (Debug), or Ignore the error. Retry will cause a User breakpoint on the error, Abort will throw a DistiException describing the error, and Ignore does nothing.

If none of the aforementioned symbols are defined, this function does nothing, and does not evaluate exp.

Note
Use this function instead of the deprecated DistiAssert() macro for checks that should be tested in Debug builds only.

◆ GLS_UNUSED

#define GLS_UNUSED (   exp)
Value:
do \
{ \
(void)sizeof( exp ); \
} while( 0 )

Convenience macro to quiet warnings about unused return values.

◆ GLS_VERIFY

#define GLS_VERIFY (   exp)    (void)( ( exp ) || ( ::disti::GlsVerify( #exp, __FILE__, __LINE__ ), 0 ) )

The GLS_VERIFY() macro has the following behavior:

  1. If a callback is registered with SetGlsVerifyHandler(), that handler is invoked when exp is false.
  2. If no handler is registered and the exp is false, on Windows GLS_VERIFY() will popup a message box allowing the user to Abort, Retry (Debug), or Ignore the error. Retry will cause a User breakpoint on the error, Abort will throw a DistiException describing the error, and Ignore does nothing.
Note
Use this function instead of the deprecated DistiAssert() macro for checks that should be tested in both Debug and Release builds.
