실시간 운영체계 Q+를 위한 C 표준 라이브러리 설계 및 구현 = The Design and Implementation of C Standard Library for RTOS Q+

다국어 초록 (Multilingual Abstract)

This paper describes the design and implementation of C standard library for real-time operating system Q+, that is being developed for the internet appliance. The C library in the real-time operating system should be defined according to the standard interface and support the concurrent execution of threads. The implemented C standard library is reentrant and follows POSIX.l standard interface. And, the C standard library functions, which are adequate to the Q+ application and commonly provided by commercial real-time operating systems, are selected among POSIX.l standard functions. The C standard library is implemented on the Q+ kernel and D-TV set-top box according to the implementation sequence, which is determined by analyzing the relation of function calls.
