[since Qt Quick Ultralite (Platform) 3.0] QUL_PLATFORM_ASSERT(expression)

Evaluates a platform assertion.

Calls Qul::Platform::PlatformContext::error with the current line number and file location if the expression evaluates to false.

This macro is intended for platform-specific assertions in platform implementation code.

In debug builds, the full filename is passed to Qul::Platform::PlatformContext::error. In release builds, only the string "L" (Line) is passed.

Example:

QUL_PLATFORM_ASSERT(initDisplayInterface() == kStatus_Success);

This macro was introduced in Qt Quick Ultralite (Platform) 3.0.

See also Qul::Platform::PlatformContext::error and QUL_PLATFORM_DEBUG_ASSERT.

[since Qt Quick Ultralite (Platform) 3.0] QUL_PLATFORM_DEBUG_ASSERT(expression)

Evaluates a platform assertion in debug builds only.

Calls Qul::Platform::PlatformContext::error with the current line number and file location if the expression evaluates to false.

Similar to QUL_PLATFORM_ASSERT, but only evaluates the assertion in debug builds. In release builds (NDEBUG defined), this macro compiles to a no-op.

This macro is useful for assertions that check conditions which are expensive to evaluate or are only relevant during development.

Example:

QUL_PLATFORM_DEBUG_ASSERT(bufferSize > 0 && bufferSize <= MAX_BUFFER_SIZE);

This macro was introduced in Qt Quick Ultralite (Platform) 3.0.

See also Qul::Platform::PlatformContext::error and QUL_PLATFORM_ASSERT.
