FIELD: physics; computer technology.
SUBSTANCE: present invention pertains to computer technology. Device has circuit for receiving a request from an application, circuit for determining the operation mode of the requesting application, circuit for calling the function using interruption and circuit for indirect function calling. The method involves a stage for receiving a request from the function calling application, a stage for determining the operation mode of the application, and a stage for calling the function using interruption if the application is executed in non-privileged mode. The function is executed in the same task as an application. The method also involves a stage for indirect function call if the application is executed in privileged mode.
EFFECT: provision for access to procedures of privileged modes of applications, executed in privileged or non-privileged mode.
