*
* \note The returned pointer is of type void* as its type is opaque,
* implementation dependent (jmp_buf is an array type not the type of
* one element of an array).
* \note This function is intended to provide the parameter of the
* setjmp() function to set-up where mbedtls_param_failed() should
* long-jump if it has to. It is foreseen to be used as:
*
* setjmp( mbedtls_test_param_failed_get_state_buf() ).
*
* \note The type of the returned value is not jmp_buf as jmp_buf is an
* an array type (C specification) and a function cannot return an
* array type.
*
* \note The type of the returned value is not jmp_buf* as then the return
* value couldn't be used by setjmp(), as its parameter's type is
* jmp_buf.
*
* \return Address of the object of type jmp_buf holding the execution state
* information used by mbedtls_param_failed() to do a long jump.
