SLANG_ASSERT_ON_FAIL

#define SLANG_ASSERT_ON_FAIL

(

x

)

值:

    {                           \
        SlangResult _res = (x); \
        if (SLANG_FAILED(_res)) \
        {                       \

            return _res;        \
        }                       \
    }

Helper macro that will assert if the return code from a call is failure, also returns the failure.

值:

    {                                \
        SlangResult _res = (x);      \
        if (SLANG_FAILED(_res))      \
        {                            \

        }                            \
    }

Helper macro that will assert if the result from a call is a failure, also returns.

SLANG_HANDLE_RESULT_FAIL

#define SLANG_HANDLE_RESULT_FAIL

x

)

Set SLANG_HANDLE_RESULT_FAIL(x) to code to be executed whenever an error occurs, and is detected by one of the macros

SLANG_RETURN_FALSE_ON_FAIL

#define SLANG_RETURN_FALSE_ON_FAIL

(

x

)

值:

    {                                       \
        SlangResult _res = (x);             \
        if (SLANG_FAILED(_res))             \
        {                                   \
            SLANG_HANDLE_RESULT_FAIL(_res); \
            return false;                   \
        }                                   \
    }

Helper macro that will return false on failure.

SLANG_RETURN_NULL_ON_FAIL

#define SLANG_RETURN_NULL_ON_FAIL

(

x

)

值:

    {                                       \
        SlangResult _res = (x);             \
        if (SLANG_FAILED(_res))             \
        {                                   \
            SLANG_HANDLE_RESULT_FAIL(_res); \
            return nullptr;                 \
        }                                   \
    }

Helper macro that will return nullptr on failure.

SLANG_RETURN_ON_FAIL

#define SLANG_RETURN_ON_FAIL

(

x

)

值:

    {                                       \
        SlangResult _res = (x);             \
        if (SLANG_FAILED(_res))             \
        {                                   \

            return _res;                    \
        }                                   \
    }

Helper macro, that makes it easy to add result checking to calls in functions/methods that themselves return Result.
