-/** Allocate memory dynamically and fail the test case if this fails.
- *
- * You must set \p pointer to \c NULL before calling this macro and
- * put `mbedtls_free( pointer )` in the test's cleanup code.
- *
- * If \p length is zero, the resulting \p pointer will be \c NULL.
- * This is usually what we want in tests since API functions are
- * supposed to accept null pointers when a buffer size is zero.
- *
- * This macro expands to an instruction, not an expression.
- * It may jump to the \c exit label.
- *
- * \param pointer   An lvalue where the address of the allocated buffer
- *                  will be stored.
- *                  This expression may be evaluated multiple times.
- * \param length    Number of elements to allocate.
- *                  This expression may be evaluated multiple times.
